Headers

Idempotency-Keystring

A unique string to identify this request to the server. The key can be up to 255 characters. You can safely retry requests with the same idempotency key within 24 hours of making the first request. This prevents sending duplicate data to your trading partners in case of network errors or other intermittent failures. Learn more.

Request body

characterSet'Basic' | 'Extended' | 'ExtendedHipaa'

When generating EDI, the character set determines the set of characters allowed in the EDI message. Characters outside of the specified set (after applying any repairs specified in RepairOptions) will result in an error.

{"stackTrail":"components:schemas:CreatePartnershipOutboundTransactionRequestContent:properties:transaction","oasType":"schema","type":"unknown","description":"The data for an EDI transaction. If you are not using a mapping, this transaction data must be < 5MB and the shape should match the [Guide JSON](https://www.stedi.com/docs/edi-platform/operate/transform-json/guide-json) format for the specified outbound transaction setting. If you are using a mapping, this transaction data must be < 4MB and the shape must match the source schema for the specified mapping."}
filenamestring

Set a custom name for the generated EDI file. Stedi overwrites files with the same name, so we recommend making the filename unique by including a timestamp or other identifier. If you do not specify a filename, Stedi autogenerates a unique name using the same ID generated for the fileExecutionId.

fragmentGroupIdsstring[]

Specify the fragment groups to include when creating this transaction. You can only generate EDI with a fragment group once. After you include a fragment group in generation call, Stedi locks the fragment to prevent accidentally generating transactions with duplicate data.

mappingIdstring

Specify a mapping ID to transform the transaction data to Guide JSON format. You can find the mapping ID on the Mappings page in the Stedi portal.

Response
