Backend API

The backend API is used by your SaaS server to send messages and sync your users profiles.
In Notifuse, a notification is not a message, it defines which channels the messages will be sent to and contains templates for each language.
When you want to notify your users, you will actually send a message.
The backend API endpoint is: https://api.notifuse.com/ and the data is sent as JSON.

Authentication
All the following methods require to be authenticated with the Authorization HTTP header and your project API Key like this: Authorization: Bearer YOUR_PROJECT_API_KEY
The project API Key is provided in your projects settings.
Send messages
When you send a message to a user, the required fields are notificationId and userId. If the user you are sending a message to, doesn't exist yet in Notifuse, it will be automatically created. The user profile fields (userEmail, userTelephone...) provided with your message, will update the user profile in Notifuse if missing.
The messages.send endpoint accepts a batch of 50 messages max. Messages will be processed in parallel, and emails/sms are sent synchronously.
If you don't provide a unique id for your messages, Notifuse will generate one. If you provide an id and you send it many times, an error "id/exists" will be returned for your message.
The endpoint returns the results for each message. If nothing bad happened on the Notifuse side, the ok field will be true. 
If an error occurred within Notifuse, the ok field will be false and the error field will be set. 
If an error occurred with the email and/or SMS provider, the ok field will still be true but the emailError and/or smsError fields will be set.
