Make sure to fill in the correct field corresponding to the correct Plaid API endpoint. For example, if you call the Plaid transactions API, you should set plaidData.transactionsResponse to be the JSON string containing the response. Note that the response fields in plaidData are all optional and you may populate as many or few as you would like, as long as an authResponse is sent at least once per account. Important note: You must provide an authResponse at least once per customer bank account so that we can store the mapping from bank account to Plaid account ID. ## OpenAPI ````yaml /api_reference/nft.yaml get /banks/transactions openapi: 3.1.0 info: version: '1.0' title: NFT API summary: API to enable direct NFT purchasing description: Reference for Sardine Crypto API servers: - url: https://api.sandbox.sardine.ai/v1 description: Sandbox - url: https://api.sardine.ai/v1 description: Prod Server security: - {} paths: /banks/transactions: get: tags: - Banks summary: Send bank information description: >- Simply populate the appropriate field in the plaidData object.
