Type Alias PreDecisionGatewayEventPromises

Dynamically allow to get a predecision with a extra request to external promises from a custom document event. You are allowed to add multiple promises but the first resolved one which resolves a predecision gets respected. If a promise returns a non-valid predecision (e.g. void) it is ignored (useful to delay the appearance of the cookie banner programmatically).

Example: Delay the cookie banner by 15 seconds

document.addEventListener("RCB/PreDecision/Promises", ({ detail: { promises } }) => {
  promises.push(new Promise((resolve) => setTimeout(resolve, 15000)));
});
Copy

Example: Do not show a cookie banner but only allow essential services

document.addEventListener("RCB/PreDecision/Promises", ({ detail: { promises } }) => {
  promises.push(Promise.resolve("essentials"));
});
