Migration

Migrating a Zapier or Make automation to a new geocoding host

Automations built in Zapier or Make often include a geocoding step tucked into a larger workflow: a new lead comes in through a form, its address gets geocoded to check territory assignment, and the result triggers a routing decision further down the chain. These workflows are frequently built by someone without a software engineering background, using whichever pre-built app connector or generic HTTP module the platform offered at the time, which changes what a migration actually looks like compared to a custom codebase.

If your current geocoding step uses a dedicated app connector, a first-party integration built by Zapier or Make specifically for the provider in question, migrating to a provider without an equivalent dedicated connector means switching that step to a generic HTTP or webhook module instead, configured to call the new provider's API directly. This is a real change in how the automation is built, not just a credential swap, and it is worth testing the replacement step thoroughly in an isolated test scenario before touching a live, production automation that other parts of a business depend on.

Specific steps for making this switch:

  1. Duplicate the existing automation in the platform's builder rather than editing it in place, so the working version keeps running until the replacement version is fully tested
  2. Replace the geocoding step with a generic HTTP module, configured with the new provider's endpoint and authentication, since a query parameter key or an Authorization: Bearer header (both supported here) is straightforward to configure in a generic HTTP module without needing a dedicated connector
  3. Map the response fields manually in the automation's data mapping step, since a generic HTTP module returns raw response data that needs to be explicitly mapped to whatever fields later steps in the automation expect, unlike a dedicated connector which often does this mapping automatically
  4. Test with a range of real inputs, including edge cases like partial addresses or unusual formatting, since this is exactly the kind of testing that is easy to skip in a no-code tool where the "code" itself is not visible for review the way a script would be
  5. Switch the trigger from the test version to the duplicated, verified automation, and only then deactivate the original once you have confirmed the new one is running correctly on live data for a short period

Because a compatibility host reproduces a familiar provider's exact response shape, if your original automation's geocoding step happened to call a provider with a matching compatibility host here, the field mapping in step 3 above may closely resemble the mapping your original connector already used internally, which can meaningfully shorten this migration. The full list of compatibility hosts is at /compatibility/, worth checking before assuming a from-scratch field mapping is necessary.

For a business-critical automation, the extra caution of testing in a duplicate rather than editing live is worth the small amount of extra setup time, since a broken lead-routing automation tends to be noticed quickly and by people outside the technical team.
