Mock sample for your project: Zettle Product Library API

This is the koomalooma Partner API. koomalooma is the first Loyalty BPaaS (Business Process as a Service) for mobile and web companies. With koomalooma merchants issue points for actions their customers / users make on your mobile or web store, for example a purchase or a referral. koomalooma takes care of all the rest, from signing up users, keeping track of points and delivering rewards in over 80 countries. koomalooma offers an easy to integrate API and web backend to configure loyalty campaigns and track performance. You can find more at http://support.koomalooma.com

The Metadata API has operations that retrieve configuration details pertaining to the different eBay marketplaces. In addition to marketplace information, the API also has operations that get information that helps sellers list items on eBay.

Hereafter is the documentation of the private API of Pims: Pointages Intelligents pour le Monde du Spectacle. This API is designed for 3rd-party softwares, editors and partners. Its main purpose is to give access the core data of a Pims customer (i.e. events, ticket counts and promotions).
Authentication
The API uses basic access authentication, meaning you will need a username and password to get authorized.
As each customer in Pims has its own domain (e.g. caramba.pims.io, gdp.pims.io...), each credentials will be valid for one domain/customer only. If you need dedicated credentials for one domain, please contact us. (In any case, we will need an explicit agreement from the customer before we create these credentials.)
To make your life easy, you can try all endpoints with the public credentials below, pointing to our demo domain:
Base path: https://demo.pims.io/api
Username: demo
Password: q83792db2GCvgYVdKpU3yG3R
Response format
The API returns JSON and matches the HAL specification. The Content-Type of each response will be application/hal+json, unless an error occurs.
Please note that this documentation describes all responses “as if” they were plain JSON. The specificities of HAL are ignored on purpose, in order to remain compact and avoid repetition.
So when you read in the doc:
{"id" : 123,"property1" :"Lorem ipsum","object" : {"id" : 456,"property2" : 7.89
}
}
... you'll get in the Real World®:
{"id" : 123,"property2" :"Lorem ipsum","embedded" : {"object" : {"id" : 456,"property2" : 7.89,"links" : {"self" : {"href" :"https://api.mydomain.com/other-item/456"
}
}
}
}"_links" : {"self" : {"href" :"https://api.mydomain.com/item/123"
}
}
}
Errors
Errors return JSON too and tries to match the Problem Details for HTTP APIs specification. If it does not match this spec, that's either a bug or a compatibility issue. Please contact us to solve the problem.
The Content-Type of errors will be application/problem+json. The content will match the following JSON:
Filtering and sorting
Every textual filter (e.g. /events?label=U2) and/or sort (e.g. /events?sort=label) performed with the API uses UTF8UNICODECI collation, meaning it is:
Case insensitive: “Chloé” will be considered the same as “CHLOÉ”;
Diacritic insensitive: “Chloé” will be considered the same as “Chloe”.
When performing a sort, it will always be ascending by default. To make it descending, just use a minus sign (-) in front of the parameter value (e.g. /events?sort=-label).
I18n
In responses, some labels can be translated (e.g. promotion types, event input types, etc.). These translatable labels are clearly indicated in the documentation below.
By default, they will be displayed in English, but you can change this behaviour via the Accept-Language header. E.g., use fr as a value for French.
PHP SDK
We provide a simple yet convenient SDK for the PHP language, see the Github page of the project.
And now?
Generaly, you will start by fetching one or more events. An event can be anything that occurs in one venue at one given date and time: a concert, a play, a match, a conference, etc. Additionnally, you can explore the series: a series is just a group of events (e.g. a tour or a festival).
Once you retrieved the events you were interested in, you can look for the sales ( ticket counts):
Get a quick overview with /events/:id/ticket-counts
Or get a full insight by calling these endpoints:
/events/:id/categories
/events/:id/channels
/events/:id/ticket-counts/detailed
Eventually, you may also want to fetch the promotions. A promotion can be anything meant to leverage the sales: ads, marketing campaigns, buzz or news around the event, etc. A promotion can be linked to any combination of events and/or series.

The Recommendation API returns information that sellers can use to optimize the configuration of their listings on eBay. Currently, the API contains a single method, findListingRecommendations. This method provides information that sellers can use to configure Promoted Listings ad campaigns to maximize the visibility of their items in the eBay marketplace.

Who is this for?
This documentation is for developers creating their own integration with Feedback's API. If you are doing a standard integration, there's a really easy Javascript integration that you should know about before you go to the effort of building your own integration.
Authentication
API calls generally need to be authenticated. Generate an API Key at https://feedback.pendo.io/app/#/vendor/settings?section=integrate. This key should then be added to every request as a request header named 'auth-token' (preferred), or as a query parameter named 'auth-token'.
Endpoint
API endpoint is https://api.feedback.eu.pendo.io / https://api.feedback.us.pendo.io depending where your datacenter is located.
Notes
API endpoints are being added to this documentation as needed by customers. If you don't see an endpoint you need please contact support and if it exists we'll publish the docs here. The 'try it out' feature on this documentation page will probably be blocked by your browser because the Access-Control-Allow-Origin header has its value set by the Feedback server depending on your hostname.
Generating client code
This documentation is automatically generated from an OpenAPI spec available here. You can use Swagger to auto-generate API client code in many languages using the Swagger Editor

reverb

Service for providing information to sellers about their listings being non-compliant, or at risk for becoming non-compliant, against eBay listing policies.

The Charity API allows third-party developers to search for and access details on supported charitable organizations.

Documentation of the Billbee REST API to connect a Billbee account to external aplications.
Endpoint
The Billbee API endpoint base url is https://app.billbee.io/api/v1
Activation
You have to enable the API in the settings of your Billbee account. In addition you need a Billbee API Key identifying the application you develop. To get an API key, send a mail to [email protected] and send us a short note about what you are building.
Authorization & security
Because you can access private data with the Billbee API, every request has to be sent over https and must
Contain a valid API Key identifying the application/developer. It has to be sent as the HTTP header X-Billbee-Api-Key
Contain a valid user login with billbee username and api password in form of a basic auth HTTP header
Throttling
Each endpoint has a throttle of max 2 requests per second per combination of API Key and Billbee user.
When you exceed these 2 calls, the API will return a HTTP 429 status code

Note: This is a (Limited Release) API available only to select developers approved by business units. Enables a seller adding an ad or item on a Partner's site to automatically create an eBay listing draft using the item details from the Partner's site.

The Negotiations API gives sellers the ability to proactively send discount offers to buyers who have shown an "interest" in their listings. By sending buyers discount offers on listings where they have shown an interest, sellers can increase the velocity of their sales. There are various ways for a buyer to show interest in a listing. For example, if a buyer adds the listing to their Watch list, or if they add the listing to their shopping cart and later abandon the cart, they are deemed to have shown an interest in the listing. In the offers that sellers send, they can discount their listings by either a percentage off the listing price, or they can set a new discounted price that is lower than the original listing price. For details about how seller offers work, see Sending offers to buyers.
