Nothing is paid until someone approves the bill in the Meow dashboard. - **Attachments**: upload invoices and supporting documents to a bill. - **Bulk loads**: send an `Idempotency-Key` with every create so a retry never duplicates a bill. Drafting is capped at 500 bills per rolling 24 hours per creator — your entity key, or the user a user-scoped key acts as. Creates past the cap return `429 Too Many Requests`. ### Billing API The Billing API lets you create and manage invoices and collect payments: - **Product management**: create and manage products with custom pricing. - **Customer management**: maintain invoicing customers with their addresses. - **Invoice creation**: generate invoices with line items, discounts, and custom notes. - **Payment options**: accept payments via ACH, wire, international wire, card, and USDC. - **Collection accounts**: configure accounts for payment collection. ### Getting Started Authenticate by sending your API key in the `x-api-key` request header. To scope requests to a specific entity, include the `x-entity-id` header. Use the `/api-keys/accessible-entities` endpoint to list all entities accessible by your API key. ### Rate Limits Each API key has a limit of 1,200 requests per minute, unless Meow has agreed a different limit with you. The limit works as a token bucket: you can spend the whole minute at once, and requests return steadily over the minute. Responses carry the `RateLimit-Policy` and `RateLimit` headers. They show your limit, the requests you have left, and the seconds until your full limit is back. These headers are informational today: going over the limit is logged, not rejected. A separate, coarser safeguard protects the API from abusive traffic and can reject requests with `429 Too Many Requests`. It returns a `Retry-After` header and a body with `error_code` set to `rate_limited` and a `message`, but not the quota headers above. Wait at least `Retry-After` seconds and add a small random delay. If the retry is limited again, back off exponentially. Send an `Idempotency-Key` when you retry a request that creates something or moves money. ### Error Responses Errors return JSON with `code`, `message`, and `debug_message`. The `code` aligns with FDX where possible; use `debug_message` for troubleshooting only. Common error codes: - `500`: Internal server error - `501`: Subsystem unavailable - `503`: Scheduled maintenance - `601`: Data not found - `602`: Customer not authorized - `701`: Account not found - `703`: Invalid input (including invalid date ranges) - `704`: Account type not supported - `705`: Account is closed - `801`: Transaction not found contact: name: Meow url: https://meow.com/ email: support@meow.com version: 1.0.0 license: name: Proprietary url: https://www.meow.com/terms-of-service servers: -
