Webhook (Optional)
Add the X-Webhook-URL header to your submit request to receive a POST callback when the job completes — no polling required.
Webhook Headers
| Header | Required | Default | Description |
|---|---|---|---|
X-Webhook-URL | Yes (to enable) | — | HTTPS endpoint on your server that will receive the POST callback. Must respond 2xx within a few seconds (process async if needed). |
X-Webhook-Mode | No | terminal | terminal — fires once at the final status (COMPLETED/FAILED/ERROR). sync — fires on every poll cycle plus the terminal event, and caps the queue’s polling delay at 15s for tighter progress updates. |
Example: enable webhook
X-Webhook-URL: https://your-server.com/webhook/callback
X-Webhook-Mode: terminal
Callback Payload
Your endpoint receives a POST application/json with the same shape as the GET /v2/requests/status/{request_id} response. Example terminal callback (mode terminal):
{
"request_id": "nano-banana-2_019dxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
"status": "COMPLETED",
"model_id": "nano-banana-2",
"error": null,
"output": {
"media_url": [

"updated_at": "2026-05-22 13:19:23",
"completed_at": "2026-05-22 13:19:23"
}
Failure callback shape

"request_id": "nano-banana-2_019dxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",

"model_id": "nano-banana-2",
"error": "Description of the error",
"output": null,
"created_at": "...",
"updated_at": "...",
"completed_at": "..."
}
Delivery semantics
- terminal mode (default) — exactly one
POSTwhen the request reaches a terminal status. No callback duringPROCESSING. - sync mode —
POSTon every status poll (with delay capped at ~15s) plus a finalPOSTat terminal status. Use when you want progress updates. - Idempotency — use
request_idas your idempotency key. Network retries can deliver the same callback more than once; your handler must tolerate duplicates. - Response — respond
200 OKwithin a few seconds. The queue does not block on slow handlers, but persistent failures may stop further deliveries. - HTTPS required — plain
http://URLs are rejected.

Webhook (Optional)
Add the X-Webhook-URL header to your submit request to receive a POST callback when the job completes — no polling required.
Webhook Headers
| Header | Required | Default | Description |
|---|---|---|---|
X-Webhook-URL | Yes (to enable) | — | HTTPS endpoint on your server that will receive the POST callback. Must respond 2xx within a few seconds (process async if needed). |
X-Webhook-Mode | No | terminal | terminal — fires once at the final status (COMPLETED/FAILED/ERROR). sync — fires on every poll cycle plus the terminal event, and caps the queue’s polling delay at 15s for tighter progress updates. |
Example: enable webhook
X-Webhook-URL: https://your-server.com/webhook/callback
X-Webhook-Mode: terminal
Callback Payload
Your endpoint receives a POST application/json with the same shape as the GET /v2/requests/status/{request_id} response. Example terminal callback (mode terminal):
{
"request_id": "nano-banana-pro_019dxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
"status": "COMPLETED",
"model_id": "nano-banana-pro",
"error": null,

"error": "Description of the error",
"output": null,
"created_at": "...",
"updated_at": "...",
"completed_at": "..."
}
Delivery semantics
- terminal mode (default) — exactly one
POSTwhen the request reaches a terminal status. No callback duringPROCESSING. - sync mode —
POSTon every status poll (with delay capped at ~15s) plus a finalPOSTat terminal status. Use when you want progress updates. - Idempotency — use
request_idas your idempotency key. Network retries can deliver the same callback more than once; your handler must tolerate duplicates. - Response — respond
200 OKwithin a few seconds. The queue does not block on slow handlers, but persistent failures may stop further deliveries. - HTTPS required — plain
http://URLs are rejected.

Webhook (Optional)
Add the X-Webhook-URL header to your submit request to receive a POST callback when the job completes — no polling required.
Webhook Headers
| Header | Required | Default | Description |
|---|---|---|---|
X-Webhook-URL | Yes (to enable) | — | HTTPS endpoint on your server that will receive the POST callback. Must respond 2xx within a few seconds (process async if needed). |
X-Webhook-Mode | No | terminal | terminal — fires once at the final status (COMPLETED/FAILED/ERROR). sync — fires on every poll cycle plus the terminal event, and caps the queue’s polling delay at 15s for tighter progress updates. |
Example: enable webhook
X-Webhook-URL: https://your-server.com/webhook/callback
X-Webhook-Mode: terminal
Callback Payload
Your endpoint receives a POST application/json with the same shape as the GET /v2/requests/status/{request_id} response. Example terminal callback (mode terminal):

Webhook (Optional)
Add the X-Webhook-URL header to your submit request to receive a POST callback when the job completes — no polling required.
Webhook Headers
| Header | Required | Default | Description |
|---|---|---|---|
X-Webhook-URL | Yes (to enable) | — | HTTPS endpoint on your server that will receive the POST callback. Must respond 2xx within a few seconds (process async if needed). |
X-Webhook-Mode | No | terminal | terminal — fires once at the final status (COMPLETED/FAILED/ERROR). sync — fires on every poll cycle plus the terminal event, and caps the queue’s polling delay at 15s for tighter progress updates. |
Example: enable webhook
X-Webhook-URL: https://your-server.com/webhook/callback
X-Webhook-Mode: terminal
Callback Payload
Your endpoint receives a POST application/json with the same shape as the GET /v2/requests/status/{request_id} response. Example terminal callback (mode terminal):
{
"request_id": "nano-banana_019dxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
"status": "COMPLETED",
"model_id": "nano-banana",
"error": null,
"output": {

"updated_at": "2026-05-22 13:19:23",

Failure callback shape

"model_id": "nano-banana",
"error": "Description of the error",
"output": null,
"created_at": "...",
"updated_at": "...",
"completed_at": "..."
}
Delivery semantics
- terminal mode (default) — exactly one
POSTwhen the request reaches a terminal status. No callback duringPROCESSING. - sync mode —
POSTon every status poll (with delay capped at ~15s) plus a finalPOSTat terminal status. Use when you want progress updates. - Idempotency — use
request_idas your idempotency key. Network retries can deliver the same callback more than once; your handler must tolerate duplicates. - Response — respond
200 OKwithin a few seconds. The queue does not block on slow handlers, but persistent failures may stop further deliveries. - HTTPS required — plain
http://URLs are rejected.
