API keys generation and IP Address whitelisting

  1. How do we know what is the campaignID ?

  2. How can I obtain my API keys earlier for testing?

    • You can now obtain your API keys on test.postman.gov.sg. Read here for more information on calling Postmanโ€™s SMS API.

  3. When can agencies test out the Postman API endpoints?

    • You can now test Postman out on test.postman.gov.sg.

  4. Regarding Authentication - can we have more information on bearer auth? Are we going to call a token API to get API keys or it will be generated from Postman Admin Portal?

  5. Does each agency get 1 API key for all systems or each system can request to get their separate unique API key?

    • API keys are tied to each campaign, each campaigns can have up to 3 API keys. The number of keys will depend on the number of campaigns your agency has generated for your system.

  6. What forms of authentication will you use for connecting via API?

    • We will issue API keys via the Admin portal for each campaign. We will also whitelist IP addresses of each agency.

  7. When do we submit our IP addresses for whitelisting?

    • This will be done in the campaign creation flow. Refer to our API documents for more information.

  8. Is there any firewall that we need to open to allow our API gateway to reach postman API gateway ?

    • You will need to whitelist your IP addresses with us before you can obtain the API keys for integration.

  9. Is whitelisting the source IP address sufficient for us to use Postman to send out SMSes?

    • Yes. In addition, you will only be able to obtain your API keys after you have whitelisted your IP address.

  10. What is Postmanโ€™s IP address?

    • We do not provide our IP address, you can whitelist our domain name.

    • If you really need our IP address, you can resolve the domain to find the IP address, but you will be responsible for updating it if it changes.

  11. For 5XX server errors, will the requests be queued on Postmanโ€™s side?

    • No.
