Integrate Pixlr Services!

Pixlr provides an API to empower third-party developers to integrate Pixlr's robust editing capabilities into their own applications, fostering a dynamic ecosystem of creative tools and solutions.


A JWT token is used to authenticate and authorize the client to use the Pixlr API.
The token gets passed to the Pixlr Applications using the 'token' query parameter on any of the Application pages.
(ex: https://pixlr.com/editor/?token=eyJhbGc...gYAUKKg).


The JWT is signed using your Pixlr API secret. Using any of these algorithms:
RS256, RS384, RS512, PS256, PS384, PS512, ES256, ES256K, ES384, ES512, EdDSA, HS256, HS384, HS512

JWT tokens should only be generated on the server-side to avoid leaking credentials!
