Initiate the process of creating 1 to 2000 payees in a batch
Use the batchId in the response to query for status.
In addition to standard semantic validations, a 400 will also result if:
- there is a duplicate remote id within the batch
- there is a duplicate email within the batch, i.e. if there is a conflict between the data provided for one payee within the batch and that provided for another payee within the same batch).
The validation at this stage is intra-batch only.
Validation against payees who have already been invited occurs subsequently during processing of the batch.
