Migrating from Karvy EWB GSP
Karvy EWB GSP is acquired by ClearTax. The current Karvy APIs will be deprecated by 30th June 2020. Migrate now.
If you are currently using Karvy iflow in your SAP CPI, you can migrate to ClearTax quickly by following the below steps.
- 1.SAP EWB GSP Integration Guide (.pdf file).
- 2.SAP Cloud Integration Platform - Integration Flow Content package (.zip file).
- 3.SAP Cloud Integration Platform - Router Content package (.zip file).
- 4.NIC server public key (Sandbox and Production) (.zip file).
- 5.Register ClearTax as GSP on NIC.
- 6.ClearTax GSP SSL certificate (Sandbox and Production) (.cer file).
- 7.Externalized Parameters (Sandbox and Production)
There is no change in points 1 to 4 above.
To register ClearTax as GSP in NIC portal for production, follow this guide:
You can download the SSL certificates below:
EWB_GSP_SSL_Sandbox.cer
1KB
Binary
ClearTax EWB GSP Sandbox SSL
wildcard.cleartax.in.cer
1KB
Binary
ClearTax EWB GSP Production SSL
You need to change only 3 parameters:
karvyclient_secret, karvy_auth_url and karvy_ewaybill_url.Sandbox
Update the following parameters with the new values:
Parameter | Value |
karvyclientid | <same karvyclientid as before> |
karvyclient_secret | <please check your email or write to [email protected]> |
karvy_auth_url | https://ewb-gsp-staging.internal.cleartax.co/ewb-sandbox/v1.03/authenticate |
karvy_ewaybill_url | https://ewb-gsp-staging.internal.cleartax.co/ewb-sandbox/v1.03/ewayapi |
Production
Update the following parameters with the new values:
Parameter | Value |
karvyclientid | <same karvyclientid as before> |
karvyclient_secret | <please write to [email protected]> |
karvy_auth_url | https://ewb-gsp.cleartax.in/ewb/v1.03/authenticate |
karvy_ewaybill_url | https://ewb-gsp.cleartax.in/ewb/v1.03/ewayapi |
The following parameters will remain the same in both sandbox and production.
Parameter | Value |
nicpkalias | niccert |
nic_token_expiry | 300 |
Note: NIC public key alias value is alias you have entered as same as the alias of the NIC
public key certificate you deployed (niccert).
In your Subaccount > Applications > Subscriptions corresponding to your sandbox (pre-production), select the Web UI URL something like:
https://xxx-xxx.xxx.xxx.hana.ondemand.com/itspacesStep 1 – Add and deploy keystore
To deploy keystore, in SCPI Web UI URL, go to Monitor > Manage Security > Keystore >
Add keystore (add an alias and select the ClearTax SSL certificate) > Deploy > Confirm.
Note: To perform above operation, you need to be a tenant administrator with role
AuthGroup.Administrator.
Step 2 – Test connection
To check the connectivity with GSP, in SCPI Web UI URL, go to Monitor > Manage
Security > Connectivity Tests > TLS > Enter the ClearTax EWB GSP base URL without https (
ewb-gsp-staging.internal.cleartax.co for sandbox and ewb-gsp.cleartax.in for production) and port > Send. The reponse
should be successful.
Step 3 – Update and deploy GSP iflow
In SCPI Web UI URL, To update the GSP iflow, go to Design > select E-Waybill package > Artifacts > against the gsp iflow, click on actions icon > configure > Define the
externalized parameters as provided by ClearTax. Once parameters are
updated, click save and then deploy.
After successful deployment, check the integration flows are in
Started state by choosing
Monitor > Manage Integration Content.
Step 4 – Add user credentials per GSTIN from NIC provided by your GSP
.
In SCPI Web UI URL, To add user credentials, go to Monitor > Manage Security > Security Material > Add > User Credentials > Deploy.
You can follow the same steps to configure production environment also.
We highly recommend you to test the entire flow with all scenarios in the sandbox environment before moving to production.
In case there is any change in the API in the future, you will have to update the iFlow which will be provided by ClearTax.
In case you have received an error code from NIC, you can check the description of the code here: https://docs.ewaybillgst.gov.in/apidocs/api-error-codes-list.html
