Response Format

All data returned from the Thinkific API is in JSON format. For information on the specific fields each endpoint returns, refer to our API Reference pages.

On this page:

Date FormatLink

All dates and timestamps are returned and expected in ISO 8601 format: YYYY-MM-DDTHH:MM:SSZ


All collections returned are limited to 25 items by default. This limit can be overridden by providing a "limit" parameter in your request. You can request up to 250 items per API by overriding the limit parameter.

For example:

curl \
-H "Authorization: Bearer <access_token>"

The above request will return up to 50 collection items.

You can also specify the page within a collection of items to retrieve. This is useful in combination with the limit parameter to loop until all items have been retrieved.

For example:

curl \
-H "Authorization: Bearer <access_token>"

All endpoints that return a collection of items will also contain a meta key that provides a hash of pagination data.

For example:

      "full_name":"Bob Smith",
      "company": "A Company",
          "label":"Phone Number",

You can use the information in the pagination hash to determine whether there are more items to fetch.

Validation ErrorsLink

All create and update operations have the potential to return validation errors if you pass invalid data. The general format is:

  "errors": {
    "email": ["has already been taken"],
    "password": ["is too short (minimum is 6 characters)"]

and responses will have an HTTP status code of 422.
