Prerequisites for Using App‑to‑App Communication

Supported on all tiers:

• App‑to‑App communication requires that users install and sign in to the ProntoForms mobile app.

  Note:App‑to‑App requests sent to logged-out users fail without triggering an x‑error callback.

• To use the search action, the mobile device user must belong to a ProntoForms team that has Search enabled.

• You must use URL encoding for all App‑to‑App requests. Use UTF-8 based percent encoding for all special characters other than parentheses ( ).

• Inbound requests are supported on all tiers, but callbacks are supported only on the Advanced and Enterprise tiers.

• If you share data from forms in App‑to‑App callbacks, we recommend that you define an allow list. This limits the URLs and apps that can receive the data and guards against unintended sharing of information.

  Info:The topic Configure a Custom App‑to‑App Allow List provides detailed steps to define the URLs and apps that can receive callbacks.

• If you want to use custom callback parameters, they must be configured and saved as part of the form.

  Info:The topic Configure App‑to‑App Custom Callback Parameters provides more information about custom callback configuration.
