Sandbox Testing

Below are a list of test values you can use in the Sandbox environment to mimic real-world scenarios.

Test values are passed to to.address, which is the address field on the to object in the /mail POST data.

Simply pass the to.address values below in a POST {formType}/{documentId}/mail API call to experience the corresponding scenario. Webhooks fire for all status changes.

Test Scenarios

`to.address`	Scenario	Description
`PROCESSING_FOR_DELIVERY`	Mailing successfully created	This scenario will return a response with a status of `PROCESSING_FOR_DELIVERY`. This will send a `MAILING_PROCESSING_FOR_DELIVERY` webhook.
`IN_TRANSIT`	Mailing is en-route	This scenario will return a response with a status of `IN_TRANSIT`. This will send a `MAILING_PROCESSING_FOR_DELIVERY` webhook, followed by a `MAILING_IN_TRANSIT` webhook.
`DELIVERED`	Mailing has arrived at its destination	This scenario will return a response with a status of `DELIVERED`. This will send a `MAILING_PROCESSING_FOR_DELIVERY` webhook, followed by a `MAILING_IN_TRANSIT` webhook, followed by a `MAILING_DELIVERED` webhook.
`RETURNED_TO_SENDER`	Mailing was undeliverable	This scenario will return a response with a status of `RETURNED_TO_SENDER`. This will send a `MAILING_PROCESSING_FOR_DELIVERY` webhook, followed by a `MAILING_IN_TRANSIT` webhook, followed by a `MAILING_RETURNED_TO_SENDER` webhook.

Any value other than the test values above will result in a CREATED status.
