Do you support JSON?

We currently do not officially support JSON. While most of our APIs do return JSON correctly, some are not yet JSON ready. So JSON is not reliable at this time.

How do I download a proof?

You can download the proof from the API call POST /jobs/<id>/proof.

How do I deal with unmailable addresses?

You can use the POST /addressCorrection API to check your address list. This API will return each address in your list with 3 boolean flags: standard, international & nonmailable.

You can use this to filter out the nonMailable addresses. If you don't, our system will detect them and filter them out so that no production/postage cost is incurred on these addresses. Non-standard addresses will be printed and mailed at first class postage rate. International will be mailed at international postage rate.

How do I get a count standard, international, and unmailable addresses?

If you want just a count of the standard, international and non-mailable addresses, you can use GET /addressLists/{{addressListId}}
