REST API: API Keys
You access the Twilio API using API keys that represent the required credentials. These keys:
- Authenticate to the REST API
- Create and revoke Access Tokens
See this document for more information about your request to Twilio's REST API, or read our article on Access Tokens to learn more.
API Keys can be provisioned and revoked through the REST API or the Twilio Console. This provides a powerful and flexible primitive for managing access to the Twilio API.
For example, you might issue separate API Keys to different developers or to different subsystems within your application.
Since API Keys can be independently revoked, you have complete control of the lifecycle of your API credentials.
If your use case requires API Keys to access the /Accounts or /Keys endpoint, a Master Key needs to be used. This can be created in the Console.
| Names in REST API format | |
|---|---|
sid
|
The unique string that that we created to identify the Key resource. |
friendly_name
|
The string that you assigned to describe the resource. |
date_created
|
The date and time in GMT that the resource was created specified in RFC 2822 format. |
date_updated
|
The date and time in GMT that the resource was last updated specified in RFC 2822 format. |
Create a new API Key
If a new API Key was created successfully, Twilio will respond with a representation of the new API Key.
This representation will be the same as that returned when fetching an API Key's instance resource, but will also include the Secret field.
POST
https://api.twilio.com/2010-04-01/Accounts/{AccountSid}/Keys.json
You may only delete Keys by authenticating with the account's AccountSid and AuthToken or API Keys that have the master key flag set in the console.
Parameters
| Parameter | Description |
|---|---|
| FriendlyName | A descriptive string that you create to describe the new key. It can be up to 64 characters long. |
If successful, Twilio will respond with a representation of the new
API Key. This representation will be exactly the same as that
returned by issuing a GET to the API Key's instance resource,
except that the Secret field will be included.
For security reasons, the API Key's Secret is only returned here, when the API Key is first created. Your application should store the API Key's Sid and Secret in a secure location to authenticate to the API and generate Access Tokens in the future.
Fetch a Key resource
GET
https://api.twilio.com/2010-04-01/Accounts/{AccountSid}/Keys/{Sid}.json
Returns a representation of the API Key.
For security reasons the Secret field is ONLY returned when the API Key is first created – never when fetching the resource.
| Names in REST API format | |
|---|---|
account_sid
Path
|
The SID of the Account that created the Key resource to fetch. |
sid
Path
|
The Twilio-provided string that uniquely identifies the Key resource to fetch. |
Read a Key resource
GET
https://api.twilio.com/2010-04-01/Accounts/{AccountSid}/Keys.json
Returns a list of API Keys in this account, sorted by DateUpdated.
The list includes all API Keys. It also includes paging information.
| Names in REST API format | |
|---|---|
account_sid
Path
|
The SID of the Account that created the Key resources to read. |
Update a Key resource
POST
https://api.twilio.com/2010-04-01/Accounts/{AccountSid}/Keys/{Sid}.json
Attempts to update the fields of an API Key instance.
If successful, it returns the updated resource representation. The response will be identical to that of the HTTP GET (fetch).
| Names in REST API format | |
|---|---|
account_sid
Path
|
The SID of the Account that created the Key resources to update. |
sid
Path
|
The Twilio-provided string that uniquely identifies the Key resource to update. |
friendly_name
Optional
|
A descriptive string that you create to describe the resource. It can be up to 64 characters long. |
Delete a Key resource
DELETE
https://api.twilio.com/2010-04-01/Accounts/{AccountSid}/Keys/{Sid}.json
Deletes an API Key. This revokes its authorization to authenticate to the REST API and invalidates all Access Tokens generated using its secret.
If the delete is successful, Twilio will return an HTTP 204 response with no body.
You may only delete Keys by authenticating with the account's AccountSid and AuthToken or API Keys that have the master key flag set in the console.
| Names in REST API format | |
|---|---|
account_sid
Path
|
The SID of the Account that created the Key resources to delete. |
sid
Path
|
The Twilio-provided string that uniquely identifies the Key resource to delete. |
Login with an API key
Using a helper library for the language of your choice, you can use your API keys to authenticate and use the Twilio REST API.
