combining-requests

You can combine requests within a batch request as you like. In the example below, you combine create requests, update requests, and get requests into one batch request. Remember, that change requests have to be wrapped in a changeset() function. Put the create requests into one changeset and combine the update and delete requests into another. The GET requests are added to the batch request directly without wrapping.

Once the batch request is executed the response will be an array of sub-responses to the specific changeset and retrieve requests in the order that was given in the request. Note, that the sub-responses of a changeset don't have to be in order.

async function executeComplexBatch(
  createAddressRequests: CreateRequestBuilder<BusinessPartnerAddress>[],
  updateAddressRequests: UpdateRequestBuilder<BusinessPartnerAddress>[],
  deleteAddressRequests: DeleteRequestBuilder<BusinessPartnerAddress>[],
  getAddressByIdRequests: GetByKeyRequestBuilder<BusinessPartnerAddress>[]
) {
  // Execute batch request
  const [
    createAddressesResponse,
    updateAndDeleteAddressesResponse,
    ...getAddressesByIdResponses
  ] = await batch(
    changeset(...createAddressRequests),
    changeset(...updateAddressRequests, ...deleteAddressRequests),
    ...getAddressByIdRequests
  ).execute(destination);

  // Do something with responses
}
