Waitpoint tokens pause task runs until you complete the token. They’re commonly used for approval workflows and other scenarios where you need to wait for external confirmation, such as human-in-the-loop processes. You can complete a token using the SDK or by making a POST request to the token’s URL.
This feature is only available in the v4 beta. To upgrade to v4, see the upgrade to v4 docs.

​
Usage

To get started using wait tokens, you need to first create a token using the wait.createToken function: 
import { wait } from "@trigger.dev/sdk";

// This can be called anywhere in your codebase, either in a task or in your backend code
const token = await wait.createToken({
  timeout: "10m", // you can optionally specify a timeout for the token
});
Once you have a token, you can wait for it to be completed using the wait.forToken function: 
import { wait } from "@trigger.dev/sdk";

type ApprovalToken = {
  status: "approved" | "rejected";
};

// This must be called inside a task run function
const result = await wait.forToken<ApprovalToken>(tokenId);

if (result.ok) {
  console.log("Token completed", result.output.status); // "approved" or "rejected"
} else {
  console.log("Token timed out", result.error);
}
To complete a token, you can use the wait.completeToken function: 
import { wait } from "@trigger.dev/sdk";
// This can be called anywhere in your codebase, or from an external service,
// passing in the token ID and the output of the token
await wait.completeToken<ApprovalToken>(tokenId, {
  status: "approved",
});
Or you can make an HTTP POST request to the url it returns: 
import { wait } from "@trigger.dev/sdk";

const token = await wait.createToken({
  timeout: "10m",
});

const call = await replicate.predictions.create({
  version: "27b93a2413e7f36cd83da926f3656280b2931564ff050bf9575f1fdf9bcd7478",
  input: {
    prompt: "A painting of a cat by Andy Warhol",
  },
  // pass the provided URL to Replicate's webhook, so they can "callback"
  webhook: token.url,
  webhook_events_filter: ["completed"],
});

const prediction = await wait.forToken<Prediction>(token).unwrap();
// unwrap() throws a timeout error or returns the result   👆

​
wait.createToken

Create a waitpoint token.

​
options

The createToken function accepts an object with the following properties:
​
timeout
string
The maximum amount of time to wait for the token to be completed. Defaults to “10m”.
​
idempotencyKey
string
An idempotency key for the token. If provided, the token will be completed with the same payload if the same idempotency key is used again.
​
idempotencyKeyTTL
string
The time to live for the idempotency key. Defaults to “1h”.
​
tags
string[]
Tags to attach to the token. Tags can be used to filter waitpoints in the dashboard.

​
returns

The createToken function returns a token object with the following properties:
​
id
string
The ID of the token. Starts with waitpoint_.
​
url
string
The URL of the token. This is the URL you can make a POST request to in order to complete the token.The JSON body of the POST request will be used as the output of the token. If there’s no body the output will be an empty object {}.
​
isCached
boolean
Whether the token is cached. Will return true if the token was created with an idempotency key and the same idempotency key was used again.
​
publicAccessToken
string
A Public Access Token that can be used to complete the token from a client-side application (or another backend). See our frontend docs for more details.

​
Example

import { wait } from "@trigger.dev/sdk";

const token = await wait.createToken({
  timeout: "10m",
  idempotencyKey: "my-idempotency-key",
  tags: ["my-tag"],
});

​
wait.completeToken

Complete a waitpoint token.

​
parameters

​
id
string
The ID of the token to complete.
​
output
any
The data to complete the token with.

​
returns

The completeToken function returns an object with the following properties:
​
success
boolean
Whether the token was completed successfully.

​
Example

import { wait } from "@trigger.dev/sdk";

await wait.completeToken<ApprovalToken>(tokenId, {
  status: "approved",
});

​
From another language

You can complete a token using a raw HTTP request or from another language. 
curl -X POST "https://api.trigger.dev/api/v1/waitpoints/tokens/{tokenId}/complete" \
  -H "Authorization: Bearer {token}" \
  -H "Content-Type: application/json" \
  -d '{"output": { "status": "approved"}}'

​
wait.forToken

Wait for a token to be completed.

​
parameters

​
token
string | { id: string }
The token to wait for.
​
options
object
Options for the wait.

​
returns

The forToken function returns a result object with the following properties:
​
ok
boolean
Whether the token was completed successfully.
​
output
any
If ok is true, this will be the output of the token.
​
error
Error
If ok is false, this will be the error that occurred. The only error that can occur is a timeout error.

​
unwrap()

We provide a handy .unwrap() method that will throw an error if the result is not ok. This means your happy path is a lot cleaner. 
const approval = await wait.forToken<ApprovalToken>(tokenId).unwrap();
// unwrap means an error will throw if the waitpoint times out 👆

// This is the actual data you sent to the token now, not a result object
console.log("Approval", approval);

​
Example

import { wait } from "@trigger.dev/sdk";

const result = await wait.forToken<ApprovalToken>(tokenId);

if (result.ok) {
  console.log("Token completed", result.output.status); // "approved" or "rejected"
} else {
  console.log("Token timed out", result.error);
}

​
wait.listTokens

List all tokens for an environment.

​
parameters

The listTokens function accepts an object with the following properties:
​
status
string | string[]
Statuses to filter by. Can be one or more of: WAITING, COMPLETED, TIMED_OUT.
​
idempotencyKey
string
The idempotency key to filter by.
​
tags

​
id
string
The ID of the token.
​
url
string
The URL of the token. This is the URL you can make a POST request to in order to complete the token.The JSON body of the POST request will be used as the output of the token. If there’s no body the output will be an empty object {}.
