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 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.

Please make sure you use the correct version of the APIs for your use case. To find out the appropriate version, go to the API Docs drop down on the menu.
