Authentication
Send your Picsart API key as a bearer token on every request.
Authorization: Bearer <PICSART_API_KEY>Make a request
One endpoint serves every model: POST to /workflows/v1/models/execute with the model id and its input in the body. The nesting is deliberate — the outer params is the envelope every workflow takes, and the inner one is this model's own input. Those inner names are the same unified ones the SDK takes, so a call translates one-to-one between the two — no per-vendor naming to learn.

Response
The body arrives in the gateway's status envelope, so the output is at response.result — alongside the task id, its status and the amount charged. Asset models return url plus an items array; text models return text instead.
