Grid implements idempotency to ensure that operations can be safely retried without creating duplicate resources or processing the same request multiple times.

​
How it works

When you make a request to Grid’s API, you can include an x-idempotency-key header. If you retry a failed request with the same key, Grid ensures that the operation is only processed once.

​
Using idempotency keys

Include an x-idempotency-key header in your request: 
curl https://api.squads.xyz/grid/smart-accounts \
  -H "x-idempotency-key: payment_123_xyz" \
  -H "Content-Type: application/json" \
  -d '{
    "policies": {
      "authorities": [
        {
          "address": "0x123...",
          "permissions": ["CAN_INITIATE", "CAN_VOTE", "CAN_EXECUTE"]
        }
      ],
      "threshold": 1
    },
    "grid_customer_id": "123e4567-e89b-12d3-a456-426614174000"
  }'

​
Key requirements

  • The x-idempotency-key header is optional but recommended for POST requests
  • Keys must be unique for each operation
  • Keys are case-sensitive
  • Keys can contain letters, numbers, hyphens, and underscores

​
Validity periods

Most idempotency keys are valid for 24 hours. However, intent creation idempotency keys are only valid for 2 minutes. After this period, you must generate a new key for subsequent intent creation requests.
