Send push with OneSignal through Courier

Prerequisites

Setup

Get your OneSignal keys

In OneSignal, open accounts and keys and copy your App ID and REST API Key.

Configure in Courier

Open the in Courier, enter your App ID and REST API Key, then click “Save.”

Profile requirements

Device tokens live on the user profile rather than on the send, so one profile can hold tokens for several devices and every push provider reads them from the same place. covers the model. OneSignal addresses the recipient by PlayerId or ExternalId. Store either one once with , which merges into the profile and creates it if it doesn’t exist:

Player ID
External ID

The id OneSignal assigned the device.

courier profiles create \

With Courier MCP, save the OneSignal player id YOUR_ONESIGNAL_PLAYER_ID on user_123.

The id your own system uses, once you have set it in OneSignal.

const profile = await client.profiles.create('user_123', {
  profile: {

courier profiles create \
  --api-key "$COURIER_API_KEY" \
  --user-id user_123 \
  --profile '{"oneSignalExternalUserId":"user_123"}'

With Courier MCP, save the OneSignal external user id user_123 on user_123.

Then send to user_id and Courier resolves the address. For a one-off with no stored profile, pass it inline instead: "to": { "oneSignalPlayerID": "YOUR_ONESIGNAL_PLAYER_ID" }.

Send by user id

The call in every language, and the rest of the profile object.

Send to a recipient

Send to user id
Send to oneSignalPlayerID

Courier reads oneSignalPlayerID off the saved profile, so preferences apply and the value can change without touching this code.

With Courier MCP, send my template to this OneSignal player id with a body override.

Data mapping

OneSignal caps the size of a push payload. In automated workflows that batch sends, a data payload can exceed that cap and the send fails. Enable data mapping on the push channel to choose which fields reach the provider. covers the template setting.

Provider details

onesignal

Courier recommends routing to the channel. Naming this key in routing.channels instead is supported, and sends through just this provider.

Send to a specific provider

When that is worth doing, and what you give up: failover, channel priority, and providers you add later.
