General description

The data received through the API is associated with a station or device. This device is identified by a unique code.
To send variable value data, a POST request will be made with a JSON payload as specified below. In the case of sending images, a POST request will be made in "multipart/form-data" format as specified below.
All requests to send data will provide an API key in the HTTP header "X-API-Key", which identifies who is sending the data, and must be signed using HMAC-SHA256 provided in the HTTP header "X-Signature " as described below, using an API secret.

Send variable-value data

Frame format:
{
"HIST": {
"DATA": {
"VAR_1": 0.34,
"VAR_2": "text"
},
"VERSION": "10.0.0",
"UTC": 1518778157,
"IMEI": "APP-FARM1-CROP1"
}
}
Frames are JSON objects that represent data from a specific station at a specific date and time.

The VERSION field will remain for now always as in the example.
The UTC field will contain the UNIX timestamp associated with the data being sent.
The IMEI field will contain the unique code that identifies the station or device. Alphanumeric values and hyphens can be used. All frames that have the same value in the IMEI field will be associated to the same device.
The DATA field will contain a JSON object with the codes of the variables as keys, and their values, which may be numeric or text strings. To simulate Boolean values, it can be sent as a value of 1.0 for ON and 0.0 for OFF.
The variable codes must be agreed with Nazaríes, since by default values are not created for variables that have not been previously registered. Currently there is already an extensive list of existing values, eg temperature, humidity, etc., that can be used; If you need non-existent Nazaríes´ variables, you must register them previously.

Query example:

curl -i -XPOST -H "X-API-Key: api-key" -H "X-Signature: signature" -H "Content-Type: application/json" -H "Accept: application/json" -d '{"HIST":{"DATA":{"VAR_1":0.34,"VAR_2":"tex"},"VERSION":"10.0.0","UTC":1518778157,"IMEI":" APP-FARM1-CROP1"}}' URL

Signature calculation:

signature: Compose the text string with the information to sign:

"<<Method HTTP>><<URL of the petition>>?<<JSON frame>>"

Ex. "POSTlocalhost:8080/submitData? {"HIST":{"DATA":{"VAR_1":0.34,"VAR_2":"text"},"VERSION":"10.0.0","UTC":1518778157,"IMEI":"APP-FARM1-CROP1"}}

Sign the above text string using HMAC-SHA256, using the API secret provided by Nazaríes as a secret and encode the result in base64
localhost:8080 should be replaced by the correct URL provided by Nazaríes.
