Hello Support team,

With reference to @Kim reply ([Importing Certificates to the iOS Wallet](https://community.blockcerts.org/t/importing-certificates-to-the-ios-wallet/283)), trying to add issuer ([https://www.blockcerts.org/samples/2.0/issuer-testnet.json](https://www.blockcerts.org/samples/2.0/issuer-testnet.json)) in my iOS wallet. App throws an alert saying “Add Issuer Failed” with message as below:  
There was an error adding this issuer. This can happen when a single-use invitation link is clicked more than once. Please check with the issuer and request a new invitation, if necessary.

Could you please help me/us to add an issuer to my wallet. I mean, the step by step. I have an issuer too.

I don’t believe this issuer was meant to be imported/added to the mobile app. The introduction url in the issuer-testnet.json file is not a valid one ([https://www.issuer.org/intro/](https://www.issuer.org/intro/)).

You’d need a valid URL hosted in the introduction URL of your issuer.json file, one that will accept the request with the specified nonce, and hooked up to a DB somewhere to save off the request and recipient’s bitcoin address.

I believe what the request looks like is `{issuerIntroductionUrl}/?bitcoinAddress={userBitcoinAddress}&nonce={nonce}`

Hi

Thanks for your reply.

I am able to add `Issuer` and `Certificates` in mobile app. But when I try to `verify`, I do get `Could not get issuer profile` but when I try the same certificate through web application, its getting passed.

Any idea?
