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. ### 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: - url: https://api.meow.com/v1 description: Meow API Production - url: https://api.sandbox.meow.com/v1 description: Meow API Sandbox security: - apiKeyAuth: [] tags: - name: API Keys description: Retrieve metadata about API keys and their accessible entities. - name: Accounts description: Access and manage accounts. - name: Approvals - name: Balances description: Retrieve account balances and available funds. - name: Bills description: View and manage bills for vendor payments. - name: Cards description: Manage virtual and physical cards, and view transactions and insights. - name: Collection Accounts description: Manage accounts for payment collection. - name: Contacts description: Manage contacts for crypto and USDC transfers. - name: Customers description: Manage invoicing customers and their details. - name: Entities - name: Invoices description: Create and manage invoices. - name: Limits - name: Line Items description: Manage invoice line items. - name: Partner Onboarding description: Onboard entities using your partner API key. - name: Partner Webhooks - name: Payment Methods description: View available payment method types. - name: Payment Networks description: Manage payment networks and routing information. - name: Products description: Manage products and pricing for invoicing. - name: Routing Numbers description: Validate routing numbers and retrieve bank information. - name: Security Policies - name: Simulations description: >- Trigger simulated events — inbound transfers, card authorizations, application approval — to test integrations end-to-end without real money movement. **Not available in production**: these endpoints exist only in sandbox and development environments and return `404 Not Found` in production. - name: Tax Forms description: Retrieve IRS tax forms (1099 family) issued for accounts. - name: Transactions description: Retrieve account transaction history and details. - name: Transfers description: >- Initiate ACH, wire, book, and crypto transfers, and retrieve transfer details. - name: Webhooks description: Manage webhook subscriptions and inspect delivery history. paths: /partner/applications: post: tags: - Partner Onboarding summary: Create Application description: >- Create a new onboarding application with business details.
