Hi guys, this is a first article in series SAP API Management (SAP APIM). As you known before, I wrote some article about APIM but that just is simple to understand concepts about APIM. Today, I will write more detail about APIM.
In this article, I want to share my understand about SAP APIM and for tutorial I will follow lesson 02 – API Provisioning in CLD900 Integration Suite Exam Certificate. Use open connector connect to API Slack. Create API Provider connect to slack. Create API base on API Provider. And end, Create Product on API Business Hub.
If you cannot see as picture, kindly go to Manage Capabilities and add it.
Login to open connector tenant.
To login you have to be authenticate by admin of open connector tenant, this guy is people who create subaccount and add capabilities open connector. If you done have permission, when you login you will receiver message
If you are admin of open connector tenant, and you want to add more member in this. Kindly follow these steps.
- Logon into open connector tenant with role admin
- Go to Security on menu
- Tab identity
- Add member
When you save your setting at first time, you will receive message
Don’t worry, just remove Roles <Account admin> and save again. After that you set role admin again. It’s will work.
Ok, now login by new member we will have
Ok, next we will use SLACK to demo for this article.
Create workspace on slack
- Go to Slack
- Create account and sign in
- Create workspace and kindly note it to use later
After done, you will have
Connect to SLACK from open connector
- Login Open Connector Tenant integration suite
- Search SLACK
- Add exactly workspace on SLACK into field Name
- Add scope chat:write into OAuthScope.
Done.
Current, we can try test some API of SLACK on open connector
Create API Provider with type Open connector
In Open connector tenant, get this information in setting. This information will be used when create API provider connect to open connector.
- Login to APIM
- Go to configure
- Create
(1) – Open Connector
(2) – Your region
(3) – Value is auto populated based on the selected region.
(4) – Value is auto populated
(5) & (6) : Get from setting of open connector tenant.
Connection test we will have
Create API from API Provider
Next, we will discover and create API from API Provider.
Go to APIM
Go to Develop
Create
Create
Go to tab resource we will have
Save
Deploy
TEST API
Go to APIM
Go to Test
Select API which you need to test
Send, we will receive result
TEST on POSTMAN
NOTE
- You can see that no authentication for this API. We just add host and call. No good, no safety for this.
- We need add some policy for this API for more security. Example you can add header API key which generated by server.
Add and configuration policy for API
Go to APIM
Go to develop
Go to API which apply policy
Edit
Select Proxy Endpoint
Select PreFlow
<!–Specify in the APIKey element where to look for the variable containing the api key–>
<VerifyAPIKey async=’true’ continueOnError=’false’ enabled=’true’
xmlns=’http://www.sap.com/apimgmt’>
<APIKey ref=’request.header.apikey’/>
</VerifyAPIKey>
Save
Deploy
Test again on POSTMAN, we will receive HTTPCODE is 401
Where will we receive API key ? Next, we will create product and subscribe API in API business hub to generate API KEY.
Create PRODUCT to bundle API
Go to APIM
Go to Develop
Tab Products
Create
Go to TAB APIs
Add
Save and publish
In this step, if you receive dialog box with message can not publish API . This issue comes because you have not registered developer user in API Business HUB Enterprise.
Go to API Business HUB Enterprise ( You have to be assigned ROLES AuthGroup.SelfService.Admin, AuthGroup.API.ApplicationDeveloper)
Go to manage
Go to link Registered Users
Add yourself as an developer. Add email
Subscribe service and get API Key
Go to API Business Hub Enterprise
Choose product which you want connect . In this example, it is Slack product
Subscribe and choose new application or existing application
In screen create user, we have to determine create application for what register id, what PRODUCTS will be associated…
(2) – Register user in manage user
(3) – Product
Save
We will have API key like this
TEST POSTMAN with this API key
SUMMARY
In this article, I shared my understand about using open connector connect to API of SLACK. Create API Provider base on it and create product in API Business Hub. This is first article in series API Management in Integration Suite Standard Edition. Next article I will share How to build API Provider from Integration Flow, ODATA service. Thanks for your reading and any advise, kindly leave your comment on this. Thanks.
