Our APIs accept and return JSON in the HTTP body, and return standard HTTP response codes. You can consume the APIs directly using your favorite HTTP/REST library. We have a testing environment referred to "sandbox", which you can setup to test API calls without affecting production data. Currently, our sandbox environment is live while our production environment is under development and will be available soon. You can sign up on our Dashboard to get API keys to access Paycode API. ### Environment Use the following base URLs when making requests to the APIs: | Environment | Base URL | |---------------|------------------------------------| | Sandbox | | | Production | | ## Authentication When you sign up on our [dashboard](https://app.staging.paycodefintech.net) and create a merchant account, you are given a secret key (also referred as api-key) and a publishable key. You may authenticate all API requests with Paycode server by providing the appropriate key in the request Authorization header. | Key | Description | |-----------------|-----------------------------------------------------------------------------------------------| | api-key | Private key. Used to authenticate all API requests from your merchant server | | publishable key | Unique identifier for your account. Used to authenticate API requests from your app's client | Never share your secret api keys. Keep them guarded and secure. contact: name: Paycode Support url: https://paycodefintech.net email: Paycode@juspay.in license: name: Apache-2.0 version: 0.1.0 servers: - url: https://api.staging.paycodefintech.net description: Sandbox Environment security: [] tags: - name: Merchant Account description: Create and manage merchant accounts - name: Profile description: Create and manage profiles - name: Merchant Connector Account description: Create and manage merchant connector accounts - name: Payments description: Create and manage one-time payments, recurring payments and mandates - name: Refunds description: Create and manage refunds for successful payments - name: Mandates description: Manage mandates - name: Customers description: Create and manage customers - name: Payment Methods description: Create and manage payment methods of customers - name: Disputes description: Manage disputes - name: API Key description: Create and manage API Keys - name: Payouts description: Create and manage payouts - name: payment link description: Create payment link - name: Routing description: Create and manage routing configurations - name: Event description: Manage events - name: POS description: Point of Sale operations including balance enquiry paths: /terminals/download: post: tags: - Terminal summary: Required Download List description: Gives the list of parameters which are required to update operationId: List Required Download requestBody: description: Request body for listing required terminal files content: application/json: schema: $ref: '#/components/schemas/TerminalRequiredFilesRequest' examples: Sample Request: value: current_versions: acquirer_param_version: v3.2.0 aid_version: v1.3.0 biometric_key_version: v1.2.0 capk_version: v2.6.0 cvm_version: v1.0.9 emv_key_version: v2.7.0 file_key_version: v3.4.0 firmware_version: v2.4.2 fx_rates_version: v1.3.0 hot_cards_version: v1.1.0 pure_tags_version: v3.2.0 tac_version: v1.1.2 tms_param_version: v4.0.5 network_token: TI5vXQgbZZPHXP7TOCo0 terminal_id: term_tPYmyt3FEfKl83JiHpb2 required: true responses: '200': description: Terminal Require Download List content: application/json: schema: type: array items: $ref: '#/components/schemas/TerminalRequiredFilesResponse' examples: Sample Response: value: - file_type: AID file_version: v2.1.5 hash: >- 2e7eb7a293d2718e23c3777691adc9e16624a8b5ad9dbfa25ddcea3fdb437cc9 - file_type: CAPK file_version: v3.0.0 hash: >- 3a7eb7a293d2718e23c3777691adc9e16624a8b5ad9dbfa25ddcea3fdb437cc9 '404': description: Terminal not found security: - api_key: [] components: schemas: TerminalRequiredFilesRequest: type: object description: Request Payload for Dowload required file list required: - terminal_id - current_versions - network_token properties: terminal_id: type: string description: Terminal ID (required) current_versions: $ref: '#/components/schemas/TerminalParameterVersions' network_token: type: string description: Sessiom Token TerminalRequiredFilesResponse: type: object description: required file response required: - file_type - file_version - hash properties: file_type: $ref: '#/components/schemas/TerminalFileType' file_version: type: string description: version of the file hash: type: string description: |- checksum of the file SHA256 checksum represented as a hex string TerminalParameterVersions: type: object description: Terminal parameter versions (MOSOLO specification) properties: firmware_version: type: string description: Firmware version nullable: true acquirer_param_version: type: string description: Acquirer parameter version nullable: true tms_param_version: type: string description: TMS parameter version nullable: true aid_version: type: string description: EMV AID profiles version nullable: true capk_version: type: string description: EMV CAPK version nullable: true tac_version: type: string description: Terminal Action Codes version nullable: true cvm_version: type: string description: CVM configuration version nullable: true pure_tags_version: type: string description: PURE tag profiles version nullable: true hot_cards_version: type: string description: Hot cards list version nullable: true fx_rates_version: type: string description: Currency exchange rates version nullable: true file_key_version: type: string description: File encryption key version nullable: true emv_key_version: type: string description: EMV key version nullable: true biometric_key_version: type: string description: Biometric key version nullable: true TerminalFileType: type: string enum: - PARAMS - HOTLIST - TAC - CVM - TAGS - AID - CAPK - KEYS - FXRATES securitySchemes: api_key: type: apiKey in: header name: api-key description: >- Use the API key created under your merchant account from the Paycode dashboard.
