Push API – Webhooks
Legito’s Push API enables your application’s web server (a webhook listener) to receive instantaneous automated messages contain Document Record details (including Documents and Files) that are triggered by any Document Record Event. A Triggering Document Record Event may be any of the Event types captured by Legito’s Document Timeline (Audit Trail).
As a webhook service, our Push API actively sends (pushes) up-to-date information to your subscribed services when specified events in your Workspace occur, versus your having to “call” and retrieve information. It is this active “pushing” of information that differentiates it from REST API.
Webhooks are “user-defined HTTP callbacks” that are sent to a unique URL address (essentially the application’s phone number). They are much like SMS notifications. Webhooks are almost always faster than polling and require less work on your end.
1) Push API Settings
The first step in using Legito’s Push API is the configuration of your webhook subscription (Push Connections in your Legito Workspace.
Push Connections define what data will be sent from Legito and when, as well as to which URL address.
Push Connections can be created:
a) In a user interface by Workspace Admins, or
b) using Legito’s REST API.
To create, modify, activate, deactivate, or delete Push Connections in the Legito user interface, go to My account => Settings => Push API.
Click the “Create” button in the upper right corner of your screen to set a new Push Connection. To maintain security, each newly created Push Connection must be enabled before use. Click the corresponding “Disabled” button from the list of Push Connections to enable it.
See our REST API documentation to learn more about creating Push Connections this way including the following methods:
- get push-connection
- post push-connection
All Push Connection created via our REST API will also be displayed in the user interface.
2) Push Connection Details
Name of the Push Connection.
URL address of your application’s web server (webhook listener).
A Webhook listener must include an HTTPS URL to which Legito can POST. This URL address must be available on the public internet and not protected by a firewall.
Push Connections can be triggered by one or more Event types. It is possible to choose from any Event types captured in Legito’s Document Timeline.
Each Push Connection should have at least one triggering Event type. If you set more than one triggering Event type, each occurrence of the respective Event will trigger the Push Connection individually.
Each Push Connection can be limited to Document Records of Documents created from a selected Template Suite, or multiple Template Suites (applicable to the Document Records created from automated Templates).
Document Record Types
Each Push Connection can be limited to a selected Document Records Type, or multiple Document Record Types. (applicable to manually created Document Records).
Legito Documents exported to any supported formats (although typically Word or PDF), and/or uploaded Files, may be attached to each pushed message.
All documents (files) attached in this manner are sent encoded in Base64.
Formats of generated Legito Documents
Similar to the manual download of Legito Documents, it is possible to choose the format in which documents will be sent, including the most popular ones – Word and PDF.
If documents are attached are sent through Push connections, users familiar with utilizing Advanced Layout Designs for exporting Legito Documents to Word or PDF, will find that documents attached to pushed messages will contain documents generated according to the respective Template’s default Advanced Layout Design.
3) Pushed Information
Document Records Owner, Workflow Stage and other Document Record Properties data (excluding Chat, Approvals, and associated Document Records) are sent as meta data within each pushed message.
Based on the Push Connection configuration, the settings, names, formats, Document Record ID and Code, Template Suite ID, file size, and content (encoded in Base64) of Files, and generated Documents contained in a Document Record may also be included in the message.
The general structure of each message pushed to a webhook listener is as follows:
The precise structure of each Pushed Connection is available in Push API Logs.
Push API Logs assist with the efficient integration of your webhook listener to each Push Connection.
To view Push API Logs, go to My account => Settings => Push API and click the “Logs” button in the upper right corner of your screen.
Each Push API Log contains the following info:
- Push Connection Name
- Request Body
This section contains the precise structure of the pushed message that will help you configure your webhook listener correctly.
Due to our efforts to reduce the length of the Push API Logs, file content (data) is excluded from logs and replaced by the following text: “Base64 encoded file data is not present in logs.”
Example of the files section in Push API Logs:
“data”: “Base64 encoded file data is not present in logs.”
“fileName”: ” serviceagreement.pdf”,
“data”: “Base64 encoded file data is not present in logs.”
- Response Code
Response Code section contains a standard list of HTTP status codes. Code “200” is your preferred code. Code 0 indicates that the URL of your webhook listener is not available and the connection was not established at all.
- Response Header & Response Body
These sections are purely informative. Responses to pushed messages from your webhook listener cannot change anything in your Workspace. Modifications, or any type of standard use of your Documents or Document Records, i.e., creating / modifying Properties, saving or downloading / uploading, or applying users, should be done using Legito’s REST API.
- Response Error
Response Error section contains information that will help you find errors in the integration with the webhook listener.
If the Response Code is 200 (everything is OK), the Response Error section will be left blank.
Push API Logs are stored for 30 days. If you need more time, please contact us at firstname.lastname@example.org.
