Returns a specification to start this module under a supervisor.

See Supervisor.

HTTP GET request.

Same as get/3 but raises.

Invoked when the server is started. start_link/3 or start/3 will block until it returns.

args is the argument term (second argument) passed to start_link/3.

Returning {:ok, state} will cause start_link/3 to return {:ok, pid} and the process to enter its loop.

Returning {:ok, state, timeout} is similar to {:ok, state} except handle_info(:timeout, state) will be called after timeout milliseconds if no messages are received within the timeout.

Returning {:ok, state, :hibernate} is similar to {:ok, state} except the process is hibernated before entering the loop. See c:handle_call/3 for more information on hibernation.

Returning :ignore will cause start_link/3 to return :ignore and the process will exit normally without entering the loop or calling c:terminate/2. If used when part of a supervision tree the parent supervisor will not fail to start nor immediately try to restart the GenServer. The remainder of the supervision tree will be (re)started and so the GenServer should not be required by other processes. It can be started later with Supervisor.restart_child/2 as the child specification is saved in the parent supervisor. The main use cases for this are:

• The GenServer is disabled by configuration but might be enabled later.
• An error occurred and it will be handled by a different mechanism than the Supervisor. Likely this approach involves calling Supervisor.restart_child/2 after a delay to attempt a restart.

Returning {:stop, reason} will cause start_link/3 to return {:error, reason} and the process to exit with reason reason without entering the loop or calling c:terminate/2.

Callback implementation for GenServer.init/1.

HTTP POST request.

Same as post/4 but raises.

Make an http request. Will not raise.

• method - can be any http verb
• url - fully formatted url or an api slug.

• body - body can be any of:

  • binary
  • {:multipart, [{binary_key, binary_value}]}
• headers - [{binary_key, binary_value}]

• opts - Keyword opts to be passed to adapter (hackney/httpoison)

  • file - option to be passed if the output should be saved to a file.

Same as request/5 but raises.
