n8n Integration

Generate AI images inside your n8n workflows using HTTP Request nodes. The API responds synchronously — no polling needed.

How it works

Node 1 — POST to generate endpoint → response has image_url immediately
Node 2 — Use image_url to download, send via email, upload to S3, etc.

Submit the image generation

Add an HTTP Request node with the configuration below.

FieldValue

MethodPOST

URLhttps://api.apinanobanana.com/v1/images/generate

AuthHeader → Authorization: Bearer nb_sk_...

BodyJSON (see code panel →)

The response comes back immediately with image_url and image_base64.

Use the image URL

Use {{ $json.image_url }} in subsequent nodes to:

→Download and save to disk or cloud storage
→Send as an email attachment
→Post to Slack, Discord, or Telegram
→Store URL in a database or Airtable

Image-to-image

To edit an existing image, add image_url pointing to your source image in the request body. The URL must be publicly accessible.

Check credit balance

Add a GET node before your generation to verify sufficient credits:

FieldValue

MethodGET

URLhttps://api.apinanobanana.com/v1/account/credits

AuthHeader → Authorization: Bearer nb_sk_...
