9. More of Our Data is Living in Web Applications
Common frustrations people face with this topic are:
● How do I integrate with my Web Application?
● FME doesn’t have a connection template for my Web Application!
● I setup a connection, but it doesn’t work.
● Ok, I’m connected, but the connection is unreliable :-(
We’re here to help!

Connecting to a
New Web Service:
WhatYou Need to
Know

15. Web Connections - What are they?
● A safe and convenient way to store and reuse your
connection parameters
● A secure, named container to use in your workflows
● Use with all supported authentication protocols
● Register with Web Services from FME Form
● Different types: OAuth 2.0, Token, HTTP
Authentication
Connecting to a New Web Service: What You Need to Know

16. Two Parts
The Web Service
Connecting to a New Web Service: What You Need to Know
The Web Connection
One service, many connections

17. Key Components of a Web Service
● Token: An alphanumeric string used to authenticate and identify an application to an
API. Takes the place of a username + password.
● REST API: a set of defined constraints that allows the software to communicate with a
defined protocol, like HTTP. In web services, REST APIs serve tokens.
● JSON: Javascript Object Notation. The format used to pass data back and forth to a web
service’s REST APIs
Connecting to a New Web Service: What You Need to Know
More components based on type of web service

18. Why API Authentication Matters
● Authentication: Verifies your identity before you
can make a request.
● Authorization: Verifies that you are allowed to make
that request.
Authentication protects an API’s data, resources and
functionality.
Connecting to a New Web Service: What You Need to Know

19. Connecting to a New Web Service: What You Need to Know
401 error: no token provided in request or bad token provided
403 error: forbidden. Authenticated ok, but the token is not authorization
to access the resource requested

20. Authenticating with FME
HTTP Authentication Protocols
● Basic
● Digest
● Kerberos
● NTLM
Even More Ways to Authenticate….
● API Keys/Application Tokens
● User Tokens
● OAuth 2.0
Connecting to a New Web Service: What You Need to Know

21. Connecting to a New Web Service: What You Need to Know
Authentication Token Expiry
● For security, authentication tokens almost always
expire after time
● Duration before expiry determined by web
application providing token, not FME.
● When using token to authenticate, FME will track
when current one expires, get new one if needed

22. Connecting to a New Web Service: What You Need to Know
ok nice very nice!

23. Laying the Groundwork
● Can you access web application you are building the web service for from FME Form or
Flow machine?
● Have you reviewed web application vendor’s API Documentation?
● Review FME Form doc for reader or writer you are going to use web connection for
● Review articles in FME Community for step-by-step instructions on creating web services
for popular web applications

Building the
Web Service
Definition

25. Token Web Services
● One of common web service types (other: OAuth 2.0)
● Simpler than OAuth 2.0
● Request a token from web application’s REST API in format
specified by provider
● Token expiry time is received from the REST API
● When token expires, same process to get another (not the case
with OAuth 2.0)
Building the Web Service Definition

26. Token Web Service Key Components
Token Generation REST API:
tells FME how to make the request to get a
token
Access Token Response:
tells FME the token and expiry key names it
should expect back
API Call Parameters:
tells FME how to use the token key to make
calls to the web application

Using the
HTTPCaller:
Making API Calls

31. Introduction to the HTTPCaller and its role in web
service integration
In 2018 on the FME Community (Ideas) a user requested:
“Similar to how the Slack integration works, it
would be nice to automate the push notification of
x,y,and z to a channel within Microsoft Teams.”
Using the HTTPCaller: Making API Calls

32. Step-by-step guide for utilizing the HTTPCaller in
FME to make API calls
● Does the application that you want to interact with have an API?
● Find the documentation for the request you need to make
● How does that service authenticate?
● Start building!
Using the HTTPCaller: Making API Calls

33. OAuth 2.0 Web Service Key Components
Client ID:
is the public identifier for your application
Client Secret:
acts as a password between the client (FME) and the
service
Redirect URI:
tells the service where to send sensitive information
(tokens)
Authorization URL:
where FME will request an authorization code from
Building the Web Service Definition
How to configure the Microsoft Teams web service

34. OAuth 2.0 Web Service Key Components
Client ID
Client Secret
generate a secret for FME Flow
Redirect URI
choose desktop app (Form) or web app
(Flow)
Tenancy
for the authorization url
API permissions
control what FME is authorized to access
Building the Web Service Definition

35. Build and Test: Web Service Permissions
To make requests to the Microsoft Graph API the user will need to be authorized to access
specific resources.
Using the HTTPCaller: Making API Calls
The permissions that are needed are
listed in the API documentation.
To be authorized to send a message
the ChannelMessage.Send
permission is required.

36. Build and Test: Web Service Permissions
Using the HTTPCaller: Making API Calls
Add all required permissions to the
Azure app registration. These can be
found in the Microsoft
documentation.
To POST a message multiple HTTP
requests are required to obtain team
id, channel id and send the chat
message.
POST /teams/{team-id}/channels/{channel-id}/messages

37. Build and Test: HTTPCallers
Using the HTTPCaller: Making API Calls

38. Put it all together
Every HTTPCaller uses the same Microsoft Teams web
service, configured as a web connection user parameter

Connections

45. Sharing Web Connections within your
Organization
If you have only FME Form:
● Export/Import web service .xml definition in FME Form
● Sharing the FME Form connection storage file and the public key file on a network drive
Sharing Web Connections
Making Database and
Web Connections
Public

46. Publish to FME Flow
● Share web connections with other FME Flow users
● Create Deployment Parameters (Requires FME Flow 2023+)
Sharing Web Connections
You will need to share the connection on
FME Flow for others to use it.

47. Sharing Web Connections
● The underlying web service is uploaded with the web connection

48. Sharing Web Connections
● OAuth 2.0 Web Service?
● Don’t forget to configure on FME Flow!

49. Deployment Parameters:Your Best Option
Sharing Web Connections
very nice!

50. Deployment Parameters

54. Testing and Troubleshooting Your Web Service

55. More Errors
● HTTP Errors (i.e., 401, 403, 404)
● Timeouts
○ FME can’t reach the web application URL
● HTTPS or SSL Certificate Errors (FME Flow)
○ May need to import the ssl certificates to establish
trust
● Can you get a token outside of FME using a tool like
Postman or cURL?

56. Connection Stops Working on FME Flow
● Works for a while, then you start receiving invalid token errors
● Tokens are published with the web service, but they expire
● Confirm your web service is configured correctly on FME Flow
○ Authorize the web connection
● Use different web connections for different FME Flow instances
