# Get message status

You can use the GC Notify API to retrieve the status of one or more messages.

Message status depends on the type of message you have sent.

You can only get the status of messages that are 7 days old or newer (by default). Data retention can be configured to be anywhere between 3 and 90 days at either the service or notification level.

# Email status

Status Information
Created GC Notify has placed the message in a queue, ready to be sent to the provider. It should only remain in this state for a few seconds.
Sending GC Notify has sent the message to the provider. The provider will try to deliver the message to the recipient for up to 72 hours. GC Notify is waiting for delivery information.
Delivered The message was successfully delivered.
Failed This covers all failure statuses:
- permanent-failure - "The provider could not deliver the message because the email address was wrong. You should remove these email addresses from your database."
- temporary-failure - "The provider could not deliver the message. This can happen when the recipient’s inbox is full. You can try to send the message again."
- technical-failure - "Your message was not sent because there was a problem between GC Notify and the provider.
You’ll have to try sending your messages again."

# Text message status

Status Information
Created GC Notify has placed the message in a queue, ready to be sent to the provider. It should only remain in this state for a few seconds.
Sending GC Notify has sent the message to the provider. The provider will try to deliver the message to the recipient for up to 72 hours. GC Notify is waiting for delivery information.
Pending GC Notify is waiting for more delivery information.
GC Notify received a callback from the provider but the recipient’s device has not yet responded. Another callback from the provider determines the final status of the notification.
Sent / Sent internationally The message was sent to an international number. The mobile networks in some countries do not provide any more delivery information. The GC Notify client API returns this status as sent. The GC Notify client app returns this status as Sent to an international number.
Delivered The message was successfully delivered.
Failed This covers all failure statuses:
- permanent-failure - "The provider could not deliver the message. This can happen if the phone number was wrong or if the network operator rejects the message. If you’re sure that these phone numbers are correct, you should contact us (opens new window). If not, you should remove them from your database. You’ll still be charged for text messages that cannot be delivered."
- temporary-failure - "The provider could not deliver the message. This can happen when the recipient’s phone is off, has no signal, or their text message inbox is full. You can try to send the message again. You’ll still be charged for text messages to phones that are not accepting messages."
- technical-failure - "Your message was not sent because there was a problem between GC Notify and the provider.
You’ll have to try sending your messages again. You will not be charged for text messages that are affected by a technical failure."

# Get the status of one message

You can use the GC Notify API to get a single message status.

GET /v2/notifications/{notification_id}

# Query parameters

# notification_id (required)

The ID of the notification. You can find the notification ID in the response to the original notification method call.

You can also find it by signing in to GC Notify (opens new window) and going to the API integration page.

You can filter the returned messages by including the following optional parameters in the URL:

  • template_type
  • status
  • reference
  • older_than

# Response

If the request is successful, the response body is json and the status code is 200:

# Get the status of multiple messages

You can use the GC Notify API to find the status of multiple messages at the same time.

This API call returns one page of up to 250 messages and statuses. You can get either the most recent messages, or get older messages by specifying a particular notification ID in the older_than argument.

You can only get the status of messages that are 7 days old or newer (by default). Data retention can be configured to be anywhere between 3 and 90 days at either the service or notification level.

GET /v2/notifications

# All messages

This will return all your messages with statuses. They will display in pages of up to 250 messages each.

You can filter the returned messages by including the following optional arguments in the URL:

  • template_type
  • status
  • reference
  • older_than

# Arguments

You can omit any of these arguments to ignore these filters.

# template_type (optional)

If you specify template_type, you can filter by:

  • email
  • sms

# status (optional)

If you specify status, you can filter by each:

  • email status
  • text message status

You can leave out this argument to ignore this filter.

# reference (optional)

If you specify a reference, you can filter results by that value, an identifier that you can create if necessary. This reference identifies a single notification or a batch of notifications. It must not contain any personal information such as name or postal address. For example:

"reference": "STRING"

# older_than (optional)

Input the ID of a notification into this argument. If you use this older_than argument, the method returns the next 250 received notifications older than the given ID.

"older_than":"740e5834-3a29-46b4-9a6f-16142fde533a"

If you leave out this argument, the method returns the most recent 250 notifications.

The client only returns notifications that are 7 days old or newer. If the notification specified in this argument is older than 7 days, the client returns an empty response.

# Response

If the request is successful, the response body is json and the status code is 200.
