ENDPOINTS

An endpoint, is the entry point to a service, a process, or any other destination. So, in Thinger.io an endpoint can be defined like a target destination that can be called by devices to perform any action, like sending an email, send a SMS, call a REST API, interact with IFTTT, call a device from a different account, or call any other HTTP endpoint.
Calling those endpoints directly by devices can be complex in small microcontrollers, and would require more bandwidth in devices. This way, Thinger.io can handle endpoints calls that can be requested directly by devices, activating them by using its identifier and passing any information required. It also adds some flexibility, as the endpoint request can be dinamically changed as necessary, while the deployed code in the device remains the same.
Create Endpoint
To manage all your endpoints, it is necessary to access to the Endpoints section, by clicking in the following menu item:
Then click on the Add Endpoint button that will open a new interface for entering the endpoint details, like in the following screenshot:
Here it is necessary to configure different parameters:
Endpoint Id: Unique identifier for your endpoint (the device must use this identifier for activating the endpoint). 
Endpoint Description: Fill here any description or detailed information you need to keep about the dashboard.
Endpoint Type: Defines the endpoint type, depending on the selected type, the endpoint will present different fields. In the following sections are described some of these types.
Useful Endpoint types
Email Endpoint
An email endpoint allows sending emails from your devices. You can define your target email address, subject, and compose your email body.
The configurable parameters are the following:
Email Address: The target email address of your message.
Email Subject: The email subject.
Email Body: Allows defining the email body, that can be a plain JSON text with the data sent from your device, or a custom body that can contain also information gathered from your device.
In the following screenshot, there is an example of an email endpoint that contains some text and variables that are filled when the device calls the endpoint, adding the current temperature and humidity reported by the device. Notice that temperature and humidity variables are closed inside double brackets {{}}, so the endpoint will be expecting this information to complete the body. In the following, there is some code examples calling this endpoint.
Calling endpoints is well documented here, but it is basically required to call the endpoint by using the call_endpoint method, which requires the endpoint id, ExampleEmail in this example, and the optional data to be sent to the endpoint, which is a pson document (quite similar to JSON) with two keys named temperature and humidity holding the readings from a DHT sensor. In the following there is an example of such call.
pson data;
data["temperature"] = dht.readTemperature();
data["humidity"] = dht.readHumidity();
thing.call_endpoint("ExampleEmail", data);
Note: If you want to include a single value in the email body, you can use the double bracket {{}} without any key, and send a pson document from the device with a single value. So, the following body:
Temperature is: {{}} ºC
Can be filled with this call in the device:
pson data = dht.readTemperature();
thing.call_endpoint("ExampleEmail", data);
HTTP Endpoint
An HTTP endpoint is a generic type of endpoint that can be used to interact with any other web service or web application. So, this endpoint can be configured to make any HTTP request, by configuring the method, URL, headers, and body.
The configurable parameters are the following:
Request URL: Configure the method (GET, POST, PUT, PATCH, or DELETE), and the request URL.
Request Headers: It is possible to add headers to the request, that can be useful for adding authorizations, control caches, configure content type, etc.
Request Body: The body can be either a custom body with an specific content, or a JSON payload with the information sent by the device. In a custom body it is possible to add custom variables, like shown in the email example. This way, it is possible to create contents in different formats like XML, SOAP, etc (remember to add the adequate content-type in this case).
Telegram Bot Endpoint
This endpoint is pre-configured to send data to a telegram bot in a simple way and thus use the messaging platform to get alerts or data from the IoT devices through Thinger.io.
The next parameters need to be configured to work with telegram bot:
Bot Token: Is the bot identification and authorization stream, this parameter can be left empty on this form in order to specify it directly in the device source code with the key "token".
Chat Identifier: Is a 10 digits chat identificator that can be obtained from Telegram conversation information. It can be left empty at this configuration and be called in the source code with the key "chat".
Chat Message: Is the text and device data that wants to be sent in the message, it can be specify here or hard coded in the device to be send on the endpoint call with the key "message".
