To whitelist URLs for using the Pipedream platform, you generally need to consider the IP addresses associated with specific services, such as HTTP requests or app connections. However, specific redirect or service URLs for whitelisting are not explicitly listed in the documentation provided. For HTTP requests made using $.send.http(), you can refer to the IP addresses mentioned in the Pipedream Destinations documentation. If you’re connecting to apps with IP restrictions, you might need to whitelist the Pipedream API’s IP addresses as mentioned in the Connected Accounts documentation. If you need further assistance or specific details about redirect/service URLs, I recommend visiting Pipedream Support for more support options.
