Read MoreEver had a user wait hours to get locked out because their NFT subscription wasn’t verified in time? In Web3, even a few-second delay can make a big difference. Hence, manual checks won’t keep up. Though there are existing tools that promise to help, most of them add layers of technical complexity. As a result, you end up juggling scripts, backend servers, and APIs.
These are the bottlenecks Kwala Web3 automation can eliminate. It ensures that whenever a user holds an NFT subscription, they automatically have access to it. In this blog, we’ll learn how to execute this process in detail.
How does automated subscription verification ease your job?

With around 28.22 million NFT holders, manually checking NFT ownership, granting access, and logging usage can be very overwhelming. Automating the process ensures that:
- Users gain access immediately upon meeting the required criteria.
- Every subscription event is automatically tracked and logged.
- Frees you from repetitive checks so you can focus on building better experiences.
- Minimises errors and ensures consistent workflow execution.
This is where Web3 subscription verification using Kwala comes in.
It monitors on-chain events in real time, automatically triggers workflows, and keeps your platform perfectly in sync. Since Kwala supports your scalability, it can handle growing user activity without extra infrastructure or effort.
Steps to automate subscription verification for your platform
With Kwala, you can automate NFT ownership checks and content access without touching a backend server. It lets your platform run smoothly while your users get instant access.
Here’s how you can set it up using Kwala multi-chain workflow automation:

Step 1: Define your trigger
First, you’ve to decide what event should start the workflow. In this case, the trigger is ownership of a subscription NFT. This means that whenever a user’s wallet is verified to hold your subscription NFT, Kwala will automatically kick off the workflow.
Step 2: Prepare smart contract details
You’ll need the NFT smart contract address and chain ID (Ethereum, Polygon, etc.) so the Kwala workflow engine knows where to look. Also, make sure you have the event name, such as Transfer or any custom event your contract emits, along with the Application Binary Interface (ABI). This ensures Kwala can detect the NFT ownership with high accuracy.
Step 3: Create the workflow for backendless subscription verification with Kwala
Head to your Kwala console and click “Create Workflow.” You can name it something like subscription_verification. Then follow these steps:
- Set the execution type to “Event.”
- Choose to repeat after every event so that each NFT verification triggers the workflow.
- Enter the contract address, chain ID, event name, and ABI
Step 4: Set up the action
Now, decide what happens after ownership is verified.
- Grant API Key: Automatically issue an API key to the user so they can access your content
- Log Usage: Record each subscription verification in your billing system or analytics dashboard
This is done by adding an action block in the Kwala subscription verification. You can give it a name like grant_api_access. Now, here’s what you’ve to do:
- Set the action type to POST (API call)
- Paste your API endpoint or webhook URL
- Define the payload, such as the user wallet address, subscription level, and timestamp
Step 5: Configure execution mode for automated subscription checks, Kwala
Choose execution mode to ensure the trigger runs first, followed by the API key generation and logging action.
Step 6: Save, compile, and deploy
Finally, review the automatically generated YAML file to make sure all details are correct. Once everything looks good, hit Save → Compile → Deploy → Activate. Now your workflow is live.
