Integrate the Zapyd Delete Bank Account endpoint into my application. Endpoint: DELETE /bank/{customer_id}/{bank_id}/delete Base URL: [https://sandbox.zapyd.com/cms/api/v1](https://sandbox.zapyd.com/cms/api/v1) (sandbox) | [https://api.zapyd.com/cms/api/v1](https://api.zapyd.com/cms/api/v1) (production) Full URL (sandbox): DELETE [https://sandbox.zapyd.com/cms/api/v1/bank/\{customer\_id}/\{bank\_id}/delete](https://sandbox.zapyd.com/cms/api/v1/bank/\{customer_id}/\{bank_id}/delete) Auth headers required on every request: * X-API-KEY: your API key * X-TIMESTAMP: current Unix time in seconds * X-SIGNATURE: Base64(HMAC-SHA256(key=apiSecret, data=X-API-KEY + "|" + X-TIMESTAMP + "|" + canonicalBody)) canonicalBody = request JSON with keys sorted at every nesting level, no whitespace (separators "," and ":"), non-ASCII escaped as lowercase \uXXXX. GET requests always sign "{}" (query params are not signed). Send the exact canonicalBody string as the request body. Timestamp must be within 300s of server time. Task: Write a typed function that: 1. Accepts customer\_id and bank\_id strings 2. Builds the signed auth headers over an empty body ("{}") 3. Calls DELETE /bank/{customer_id}/{bank_id}/delete 4. Returns the deleted bank account object 5. Handles 400 (not found / access denied) and 500 errors Language: TypeScript | API Status Code | Response | Reason | | - | - | - | | 400 | Customer not found or access denied | Customer not found | | 400 | Customer not found or access denied | Customer does not belong to the organization | | 400 | Bank not found or access denied | Bank not found | | 400 | Bank not found or access denied | Bank does not belong to the Customer | | 500 | Internal Server Error. | Internal Server Error | ## OpenAPI ````yaml DELETE /bank/{customer_id}/{bank_id}/delete openapi: 3.1.0 info: title: Zapyd API description: API for Zapyd - Customer, Payout, and Webhook services license: name: MIT version: 1.0.0 servers: - url: https://sandbox.zapyd.com/pos/api/v1 description: Payout API Base URL variables: base_url: default: https://sandbox.zapyd.com - url: https://sandbox.zapyd.com/cms/api/v1 description: Customer API Base URL variables: base_url: default: https://sandbox.zapyd.com security: - ApiKeyAuth: [] TimestampAuth: [] SignatureAuth: [] tags: - name: Customer description: Customer related operations x-displayName: Customer x-traitTag: true - name: Payout description: Payout related operations - name: Webhooks description: Webhook related operations - name: Widget description: Hosted buy/sell widget session initialization paths: /bank/{customer_id}/{bank_id}/delete: delete: tags: - Bank description: >- Delete a customer's bank account.
