ExTwilio v0.5.1 ExTwilio.Capability View Source

Capability tokens are used to sign communications from devices to Twilio. You create a token on your server, specify what capabilities you would like your device to have, then pass the token to your client to use. The tokens generated are JSON Web Tokens (JWT).

Example

ExTwilio.Capability.new
|> ExTwilio.Capability.allow_client_incoming("tommy")
|> ExTwilio.Capability.allow_client_outgoing("APabe7650f654fc34655fc81ae71caa3ff")
|> ExTwilio.Capability.token
"xxxxx.yyyyy.zzzzz"

Functions

Gives the device a client name allowing incoming connections to the client identified by the provided client_name

Gives the device an application sid so that Twilio can determine the voice URL to use to handle any outgoing connection

Initialises a new capability specification with a TTL of one hour, and the account sid and auth token taken from the configuration

Sets the time at which the TTL begins in seconds since epoch

Generates a JWT token based on the requested capabilities that can be provided to the Twilio client. Supports clients with multiple capabilties

Sets the Twilio account sid used to issue the token

Sets the Twilio account auth token used to sign the capability token

Sets the TTL of the token in seconds

Link to this function allow_client_incoming(client_name) View Source
allow_client_incoming(String.t) :: t

Gives the device a client name allowing incoming connections to the client identified by the provided client_name.

Example

A device with this token will be identified as tommy

ExTwilio.Capability.allow_client_incoming("tommy")
Link to this function allow_client_incoming(capability_struct, client_name) View Source
allow_client_incoming(t, String.t) :: t
Link to this function allow_client_outgoing(app_sid) View Source
allow_client_outgoing(String.t) :: t

Gives the device an application sid so that Twilio can determine the voice URL to use to handle any outgoing connection.

Example

Outgoing connections will use the Twilio application with the SID: APabe7650f654fc34655fc81ae71caa3ff

ExTwilio.Capability.allow_client_outgoing("APabe7650f654fc34655fc81ae71caa3ff")

allow_client_outgoing(String.t, map) :: t
Link to this function allow_client_outgoing(capability_struct, app_sid, app_params) View Source
allow_client_outgoing(t, String.t, map) :: t

Initialises a new capability specification with a TTL of one hour, and the account sid and auth token taken from the configuration.

Example

ExTwilio.Capability.new
Link to this function starting_at(capability_struct, start_time) View Source
starting_at(t, non_neg_integer) :: t

Sets the time at which the TTL begins in seconds since epoch.

Example

Sets the TTL to begin on 24th May, 2016

ExTwilio.Capability.starting_at(1464096368)
Link to this function token(capability_struct) View Source
token(t) :: String.t

Example

Generates and signs a token with the provided capabilities

ExTwilio.Capability.token
Link to this function with_account_sid(capability_struct, account_sid) View Source
with_account_sid(t, String.t) :: t

Sets the Twilio account sid used to issue the token.

Example

Sets the account sid to be XXX

ExTwilio.Capability.with_account_sid('XXX')
Link to this function with_auth_token(capability_struct, auth_token) View Source
with_auth_token(t, String.t) :: t

Sets the Twilio account auth token used to sign the capability token.

Example

Sets the auth token to be XXX

ExTwilio.Capability.with_auth_token('XXX')
Link to this function with_ttl(capability_struct, ttl) View Source
with_ttl(t, non_neg_integer) :: t

Sets the TTL of the token in seconds.

Example

Sets the TTL to one hour

ExTwilio.Capability.with_ttl(3600)
