SOLUTION "Parameters missing or malformed" I found a way out. Go to the website, login, and pay for the subscription from there. The app will update accordingly and everything will be fine. I hope. Worked for me.

Cant submit card details to pay for membership. Tried two different cards and tried both scanning the card ( which didn't work on either card) and then entering the card details manually. Both cards the option to submit the card details is not active or available to submit the information and proceed any further with the payment.

I can’t renew my subscription
By David Lindgren 1 year ago
I've been having exactly the same problem as everyone else who has posted here. Won't accept payment and I'm getting the same messages that everyone else has posted on this page. I bump into loads of people at the docks who are battling with trying (and failing) to hire bikes using the app. And since the September system-wide update, paying at the machines at the docks is unbelievably slow and painful. Especially now that the '24 hour hire' option is gone. Have to go through the *full* hire process *every single time*. It's so painful, it's almost worth switching to hiring one of the myriad of electric bikes!

Is not accepting my card details. I've just created an account. It's saying details missing or malinformed. They are not malinformed.Please help.

Have been trying to purchase an annual subscription since May but no forms of payment are being accepted
By Mark bossi 1 year ago
App is crap, doesn’t retain credit card info and is asking me to put card details again, then it would say error, that card is already in use. So I’m unable to use the app now this is bullshit who designed this shit?
By Valentina Albanese 1 year ago
Same as everyone else, the app doesn't recognise payment details and I've stopped using it for this very reason! It's been months it's ridiculous
By Steve Wigmore 1 year ago
Same as everyone else. Stopped working a couple of months ago. Tried many times. Now have to use terminal which takes minutes to generate a code and leads to big queues. So frustrating!!
By Dan 1 year ago
Cannot add any card details via the app, so no way to get an annual membership - fix it!
By Gilly 1 year ago
App not working. It won't retain payment card and won't progress past 'hire now'. Please fix this as it is otherwise a discouragement to use.
By Ellie Wray 1 year ago
Unable to use app. :( SDK error message in payment. Been using the app for years just started crashing about 2 weeks ago. Deleted the app and reinstalled it but didn’t work. Tried upgrading to the annual but doesn’t work. Please fix bugs!!

The app does not retain debit card information. Fails continuously. Requests for user support are unanswered. App is crap. Stopped working months ago.

What is the point of the cycle scheme if the App doesn’t work? Why is they no work around? Why is this so difficult?
By Gary Hawkins 1 year ago
Same issue with error messages. Very very annoying
By Simon Cornwell 1 year ago
App not working, can’t put in my payment details. Not worked for a while. Please sort this out now.
By Alex Potter 1 year ago
I get the “Parameters are missing or malformed” error message on the app. I've deleted it, reinstalled it, logged out, logged in... nothing seems to work. Can you help?
By Philip Mastriforte 1 year ago
Same as everyone else. The app worked fine until about 10 days ago and now all I get is an error popup about SDK and parameters are missing. Have tried numerous times to re-enter my info....to no effect. I have checked online and it has the correct card details and have tried to re-upload card details on the app without any luck. the base stations do not accept contactless to make matters worse and then are SO SLOW to give you a physical code. Service is falling off a cliff. We are doomed!
By Justin Young 1 year ago

By Tamsin Peskett-Hall 1 year ago
Kept getting error messages when I tried to ‘renew subscription’ and use a bike today. Tried re-entering card details and got the same error messages about parameters etc
By Louis Ward 1 year ago
The app removed my payment method and won’t let me pay on any of my cards?
By James 1 year ago
Same issue - "SDK not initialised" and "Parameters missing or malformed" error messages when attempting to renew subscription. Deleted and reinstalled app but this did not solve. Had this issue both this morning and on 1 June.
By James Gosling 1 year ago
I have the same problem as everyone else here. I am unable to update my new card details through the app. Error popup says SDK and parameters are missing. It's extremely frustrating. Please fix it!
By Jim M 1 year ago
Since last week, the app, which I use every week, isn't working. I get the error message 'Parameters missing or malformed' after I've selected the location for bike hire. No options/instructions to do anything else, and nothing on the Santander bikes website. PLEASE FIX.
By Gabi 1 year ago
When trying to renew subscriptions there are two pop ups that say ‘sdk not initialised’ and then ‘Parameters are missing or malformed’. What is this problem? It’s been continuous for a week now.
By David Snowdon 1 year ago

By Oliver 1 year ago
Same as above Every time I try and use the app the payment fails - it hasn't retained my card information and after I put it in, the app just doesn't respond or allow me to progress to payment or provide a code.

Every time I try and use the app the payment fails - it hasn't retained my card information and after I put it in, the app just doesn't respond or allow me to progress to payment or provide a code.
- Limited use for actually reserving and paying for bikes, at least if your party has more than one person
- App will only allow one rental at a time
- UI needs to be updated for iPhone X
- Issues are not resolved and they end up overcharging the credit card
- Customer service completely unhelpful
- Error message when trying to rent a bike at 2 am
