Mock sample for your project: Gitlab API

The Local Search client lets you send a search query to Bing and get back search results that include local businesses such as restaurants, hotels, retail stores, or other local businesses. The query can specify the name of the local business or it can ask for a list (for example, restaurants near me).

Welcome to the POS API.
You can use this API to access all POS API endpoints.
Base URL
The base URL for all API requests is https://unify.apideck.com
We also provide a Mock API that can be used for testing purposes: https://mock-api.apideck.com
GraphQL
Use the GraphQL playground to test out the GraphQL API.
Headers
Custom headers that are expected as part of the request. Note that RFC7230 states header names are case insensitive.
| Name | Type | Required | Description |
| --------------------- | ------- | -------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| x-apideck-consumer-id | String | Yes | The id of the customer stored inside Apideck Vault. This can be a user id, account id, device id or whatever entity that can have integration within your app. |
| x-apideck-service-id | String | No | Describe the service you want to call (e.g., pipedrive). Only needed when a customer has activated multiple integrations for the same Unified API. |
| x-apideck-raw | Boolean | No | Include raw response. Mostly used for debugging purposes. |
| x-apideck-app-id | String | Yes | The application id of your Unify application. Available at https://app.apideck.com/unify/api-keys. |

Authorization
You can interact with the API through the authorization methods below.
Pagination
All API resources have support for bulk retrieval via list APIs. Apideck uses cursor-based pagination via the optional cursor and limit parameters.
To fetch the first page of results, call the list API without a cursor parameter. Afterwards you can fetch subsequent pages by providing a cursor parameter. You will find the next cursor in the response body in meta.cursors.next. If meta.cursors.next is null you're at the end of the list.
In the REST API you can also use the links from the response for added convenience. Simply call the URL in links.next to get the next page of results.
Query Parameters
| Name | Type | Required | Description |
| ------ | ------ | -------- | ------------------------------------------------------------------------------------------------------------------ |
| cursor | String | No | Cursor to start from. You can find cursors for next & previous pages in the meta.cursors property of the response. |
| limit | Number | No | Number of results to return. Minimum 1, Maximum 200, Default 20 |
Response Body
| Name | Type | Description |
| --------------------- | ------ | ------------------------------------------------------------------ |
| meta.cursors.previous | String | Cursor to navigate to the previous page of results through the API |
| meta.cursors.current | String | Cursor to navigate to the current page of results through the API |
| meta.cursors.next | String | Cursor to navigate to the next page of results through the API |
| meta.itemsonpage | Number | Number of items returned in the data property of the response |
| links.previous | String | Link to navigate to the previous page of results through the API |
| links.current | String | Link to navigate to the current page of results through the API |
| links.next | String | Link to navigate to the next page of results through the API |
⚠️ meta.cursors.previous/links.previous is not available for all connectors.
SDKs and API Clients
We currently offer a Node.js, PHP and .NET SDK.
Need another SDK? Request the SDK of your choice.
Debugging
Because of the nature of the abstraction we do in Apideck Unify we still provide the option to the receive raw requests and responses being handled underlying. By including the raw flag ?raw=true in your requests you can still receive the full request. Please note that this increases the response size and can introduce extra latency.
Errors
The API returns standard HTTP response codes to indicate success or failure of the API requests. For errors, we also return a customized error message inside the JSON response. You can see the returned HTTP status codes below.
| Code | Title | Description |
| ---- | -------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| 200 | OK | The request message has been successfully processed, and it has produced a response. The response message varies, depending on the request method and the requested data. |
| 201 | Created | The request has been fulfilled and has resulted in one or more new resources being created. |
| 204 | No Content | The server has successfully fulfilled the request and that there is no additional content to send in the response payload body. |
| 400 | Bad Request | The receiving server cannot understand the request because of malformed syntax. Do not repeat the request without first modifying it; check the request for errors, fix them and then retry the request. |
| 401 | Unauthorized | The request has not been applied because it lacks valid authentication credentials for the target resource. |
| 402 | Payment Required | Subscription data is incomplete or out of date. You'll need to provide payment details to continue. |
| 403 | Forbidden | You do not have the appropriate user rights to access the request. Do not repeat the request. |
| 404 | Not Found | The origin server did not find a current representation for the target resource or is not willing to disclose that one exists. |
| 409 | Conflict | The request could not be completed due to a conflict with the current state of the target resource. |
| 422 | Unprocessable Entity | The server understands the content type of the request entity, and the syntax of the request entity is correct but was unable to process the contained instructions. |
| 429 | Too Many Requests | You sent too many requests in a given amount of time ("rate limit"). Try again later |
| 5xx | Server Errors | Something went wrong with the Unify API. These errors are logged on our side. You can contact our team to resolve the issue. |
Handling errors
The Unify API and SDKs can produce errors for many reasons, such as a failed requests due to misconfigured integrations, invalid parameters, authentication errors, and network unavailability.
Error Types
RequestValidationError
Request is not valid for the current endpoint. The response body will include details on the validation error. Check the spelling and types of your attributes, and ensure you are not passing data that is outside of the specification.
UnsupportedFiltersError
Filters in the request are valid, but not supported by the connector. Remove the unsupported filter(s) to get a successful response.
UnsupportedSortFieldError
Sort field (sort[by]) in the request is valid, but not supported by the connector. Replace or remove the sort field to get a successful response.
InvalidCursorError
Pagination cursor in the request is not valid for the current connector. Make sure to use a cursor returned from the API, for the same connector.
ConnectorExecutionError
A Unified API request made via one of our downstream connectors returned an unexpected error. The status_code returned is proxied through to error response along with their original response via the error detail.
UnauthorizedError
We were unable to authorize the request as made. This can happen for a number of reasons, from missing header params to passing an incorrect authorization token. Verify your Api Key is being set correctly in the authorization header. ie: Authorization: 'Bearer sklive*'
ConnectorCredentialsError
A request using a given connector has not been authorized. Ensure the connector you are trying to use has been configured correctly and been authorized for use.
ConnectorDisabledError
A request has been made to a connector that has since been disabled. This may be temporary - You can contact our team to resolve the issue.
ConnectorRateLimitError
You sent too many request to a connector. These rate limits vary from connector to connector. You will need to try again later.
RequestLimitError
You have reached the number of requests included in your Free Tier Subscription. You will no be able to make further requests until this limit resets at the end of the month, or talk to us about upgrading your subscription to continue immediately.

API Design
API Styles and data formats
REST API
The API is organized around REST, providing simple and predictable URIs to access and modify objects. Requests support standard HTTP methods like GET, PUT, POST, and DELETE and standard status codes. JSON is returned by all API responses, including errors. In all API requests, you must set the content-type HTTP header to application/json. All API requests must be made over HTTPS. Calls made over HTTP will fail.
Available HTTP methods
The Apideck API uses HTTP verbs to understand if you want to read (GET), delete (DELETE) or create (POST) an object. When your web application cannot do a POST or DELETE, we provide the ability to set the method through the query parameter \_method.
Response bodies are always UTF-8 encoded JSON objects, unless explicitly documented otherwise. For some endpoints and use cases we divert from REST to provide a better developer experience.
Schema
All API requests and response bodies adhere to a common JSON format representing individual items, collections of items, links to related items and additional meta data.
Meta
Meta data can be represented as a top level member named “meta”. Any information may be provided in the meta data. It’s most common use is to return the total number of records when requesting a collection of resources.
Idempotence (upcoming)
To prevent the creation of duplicate resources, every POST method (such as one that creates a consumer record) must specify a unique value for the X-Unique-Transaction-ID header name. Uniquely identifying each unique POST request ensures that the API processes a given request once and only once.
Uniquely identifying new resource-creation POSTs is especially important when the outcome of a response is ambiguous because of a transient service interruption, such as a server-side timeout or network disruption. If a service interruption occurs, then the client application can safely retry the uniquely identified request without creating duplicate operations. (API endpoints that guarantee that every uniquely identified request is processed only once no matter how many times that uniquely identifiable request is made are described as idempotent.)
Request IDs
Each API request has an associated request identifier. You can find this value in the response headers, under Request-Id. You can also find request identifiers in the URLs of individual request logs in your Dashboard. If you need to contact us about a specific request, providing the request identifier will ensure the fastest possible resolution.
Fixed field types
Dates
The dates returned by the API are all represented in UTC (ISO8601 format).
This example 2019-11-14T00:55:31.820Z is defined by the ISO 8601 standard. The T in the middle separates the year-month-day portion from the hour-minute-second portion. The Z on the end means UTC, that is, an offset-from-UTC of zero hours-minutes-seconds. The Z is pronounced "Zulu" per military/aviation tradition.
The ISO 8601 standard is more modern. The formats are wisely designed to be easy to parse by machine as well as easy to read by humans across cultures.
Prices and Currencies
All prices returned by the API are represented as integer amounts in a currency’s smallest unit. For example, $5 USD would be returned as 500 (i.e, 500 cents).
For zero-decimal currencies, amounts will still be provided as an integer but without the need to divide by 100. For example, an amount of ¥5 (JPY) would be returned as 5.
All currency codes conform to ISO 4217.
Support
If you have problems or need help with your case, you can always reach out to our Support.

This API provides a standard for country name for the purposes of standardizing country name data, improving query results, analytics, and data merging.

Base API URL: https://api.configcat.com
If you prefer the swagger documentation, you can find it here: Swagger UI.
The purpose of this API is to access the ConfigCat platform programmatically.
You can Create, Read, Update and Delete any entities like Feature Flags, Configs, Environments or Products within ConfigCat.
The API is based on HTTP REST, uses resource-oriented URLs, status codes and supports JSON
and JSON+HAL format. Do not use this API for accessing and evaluating feature flag values. Use the SDKs instead.
OpenAPI Specification
The complete specification is publicly available here: swagger.json.
You can use it to generate client libraries in various languages with OpenAPI Generator or
Swagger Codegen to interact with this API.
Authentication
This API uses the Basic HTTP Authentication Scheme.
Throttling and rate limits
All the rate limited API calls are returning information about the current rate limit period in the following HTTP headers:
| Header | Description |
| :- | :- |
| X-Rate-Limit-Remaining | The maximum number of requests remaining in the current rate limit period. |
| X-Rate-Limit-Reset | The time when the current rate limit period resets. |
When the rate limit is exceeded by a request, the API returns with a HTTP 429 - Too many requests status along with a Retry-After HTTP header.

This API provides a similarity key used to match with other similar full name data when data fields are parsed into first name and last name components, including for purposes of deduplication, fuzzy matching, or merging of datasets. A much higher match rate will be achieved by matching on the similarity key rather than the data itself. This API is for full name data where first and last name are in separate fields. Use the Full Name Similarity Key API for first and last name data that are in the same field.

This is the interface for interacting with the Asana Platform. Our API reference is generated from our [OpenAPI spec] (https://raw.githubusercontent.com/Asana/developer-docs/master/defs/asana_oas.yaml).

This API provides a similarity key used to match with other similar country name data, including for purposes of deduplication, fuzzy matching, or merging of datasets. A much higher match rate will be achieved by matching on the algorithmically generated similarity key rather than the data itself.
