Authentication

Send your Picsart API key as a bearer token on every request.

Header

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 paramsis 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.

cURL

curl -X POST 'https://api.picsart.com/workflows/v1/models/execute' \
  -H 'Authorization: Bearer $PICSART_API_KEY' \
  -H 'Content-Type: application/json' \
  -d '{
  "params": {
    "model": "seedance-2.5-video-edit",
    "params": {
      "prompt": "A serene mountain lake at golden hour, ultra detailed",
      "aspectRatio": "adaptive",
      "resolution": "1080p",
      "videoUrl": "https://cdn.example.com/input.mp4"
    }
  }
}'

Async (submit & poll)

This model can run longer than the sync limit (~20s), so send it to /workflows/v1/models/submit, which returns a task id, and poll /workflows/v1/models/{taskId}/result until response.status is COMPLETED or FAILED.

# 1. Submit the job

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 credits charged. Asset models return url plus an items array; text models return text instead.
