All users with valid Enterprise accounts can access the Flipsnack API. Using our API, you can manage your publications just as you would in our online application. To ensure fair usage and stability of our infrastructure we have set a few limitations to this API.
Note: These limitations apply only to Flipsnack API and not the online application. If you would like to have these limitations changed for you, please
The number of uploads via the API is limited as follows:
Max 1000 uploads per month. This option is available only for Enterprise users, when purchasing or upgrading to an Enterprise account.
In case you exceed the number of uploads per month, the request will return the error code "32 - Uploads per month limit exceeded".
Note: Only successful upload requests from collection.create and flipbook.add are counted to the monthly upload limitations. Logo and background image uploads are bound only to the file and request limitations.
The files uploaded via the API must be valid files of type PDF, JPG, PNG and GIF. You can make upload requests to create new collections from PDF documents or to set background images and logos.
We recommend you to upload a single PDF document when you use the collection.create API call. If you have multiple PDF files for a single collection, you should merge them into a single file and upload it. Please keep in mind the above file limitations (100 MB and a maximum of 500 pages per document).
We limit Flipsnack API calls (both read and write) to a maximum of 3 calls per second and 30 calls per minute to ensure that system resources are distributed evenly. If you exceed the number of requests per second the API call will return the error code "31 - Requests per second limit exceeded".
We recommend spreading requests over a larger time period so you can avoid receiving this error.
Here are the error codes related to API limitations:
