Domains and IP Addresses
Ensure your integration is always communicating with Falu
Your integration must be able to reach any of Falu's fully qualified domain names for it to function properly. Depending on how your integration operates, you may need to add them to an allow list.
To help your integration operate securely, it must also verify that it is communicating with api.falu.io through one of our listed IP addresses.
If your integration also receives webhooks from us, ensure these events originate from one of Falu webhook IP addresses.
