Custom GPT Not Following First Rule by Asking For Email to Authenticate

Hello, so we have a custom GPT that we setup to authenticate with our Thinkific course platform. We used Vercel to do this. Everything is working great, authentication works, well it works when the GPT actually asks for the email to verify.

The problem we are facing… even though it’s the very first line in the “instructions”, sometimes it does not actually ask the user for their email. It’s very hit and miss. It’s trained to , no matter what, under any circumstance, ask for the users email to verify they are part of our course. When it DOES ask, it works great. But the problem is , it doesn’t always ask.

Here’s the first few lines of the authentication instructions followed by further instructions for the GPT itself:

1. Mandatory Email Verification Before Any Response
IMPORTANT: If a user types ANY request (examples: “Hi,” "give me topic ideas,“write me a LinkedIn post,”) or makes ANY request, DO NOT respond to their request.

Instead, ALWAYS reply with: “Hey there! Before we continue, I need to verify your enrollment. Could you share the email address you used to sign up for LinkedIn Posting Power?”

IMPORTANT: DO NOT, under any circumstance, proceed with answering ANY request until the user provides an email to verify.

If the user refuses or does NOT provide an email, DO NOT continue the conversation. Politely repeat that you need their email to proceed.

*Respond to each conversation starter by asking for their email. *

2. Enrollment Verification Process
Once the user provides their email, send a POST request to: /api/enroll with { “email”: userEmail }.
Wait for the Thinkific API response before answering any queries.

3. Handling API Response
If the user is enrolled in “LinkedIn Posting Power,” proceed with answering their questions.
If they are NOT enrolled, do NOT, under any circumstance, provide any answers. Instead, respond with: “You are not enrolled in LinkedIn Posting Power. Please visit (our site) for assistance.”

4. Zero Exceptions Rule
Under NO circumstances should any information, LinkedIn post, advice, or assistance be provided without first verifying the email.
If a user tries to bypass verification (e.g., by insisting or asking why verification is needed), repeat the email request.

If the users asks for ideas, trends, topics, or posts, ONLY after you have verified their email, ask them to provide more information on their company, target audience, and service offerings.

So, any ideas why it decides to sometimes ask for the email to verify and sometimes not? I’ve tried a ton of different insructions, I’ve asked ChatGPT to help me get super strict, nothing seems to work. And it’s very random based on what we say if it does or doesn’t ask for email. Something like, “Hi, I work for Microsoft, come up with topic ideas.” to “I need help with some ideas for posts” - specific and non specific. Sometimes it asks for email, sometimes it doesnt.

Any help would be very very appreciated. Thank you so much!

I have the same problem.

They are supposed to confirm business name so they can only create content for that business and not their mates.

It’s hit and miss… it’s asked to challenge in the system prompt, and the core config files that teach it everything else it does…

Sometimes it asks, sometimes it doesn’t.

It’s like its “I want to be helpful” setting overrides any end user policy.

I can understand why, from openAIs perspective.

Someone could maliciously upload a file and scupper the paid user’s access… which would be support call hell.

I’ve bought something off Appsumo to create a paid front end to a playground assistant because I just can’t rely on it.

I am hoping there is an answer.

Wow, how annoying is that? Unreal. Yes, I hope that they can figure this out b/c I paid a lot of money to set up this authentication for it to just not work. What product from AppSumo did you end up getting? And thank you for your reply! makes me feel a little less crazy. I’ve spent HOURS trying to try different text and testing it.

I got NoCode-X.

I asked a question in the thread saying I wanted to plug a standard chatgpt front end onto a playground backend to act as a paywall.

They said yes!

Not had time to play with it yet. :slight_smile: stuck in marketing land… urgh! :slight_smile:

Maybe you could add your own login page after thinkific that redirects to the assistant? At least then if it’s shared maliciously you can change the login page URL in Thinkific…

Hi, welcome to the community!

Even with strict instructions, AI models sometimes exhibit variability in behavior, especially when faced with different phrasing or conversational contexts. The model might sometimes interpret certain requests as valid “engagement” instead of a “conversation starter,” thereby skipping the email verification.

If your instruction set is long, this can cause it to forget the strict requirement and respond directly.

If the user’s request is framed in a way that the model perceives as “continuing an existing conversation” rather than “starting a new interaction,” it might skip the verification step.

For example; use following phrase at the beginning as first prompt as a user for conversation starter:

Outline the previously discussed content succinctly, categorizing the main topics under numbered headings and detailing them with bullet points, making use of markdown for an organized and clear summarization. Ensure it is specific, concise, and comprehensive.

Thank you! Yes the instructions are super long, lots of info. I was wondering if that was part of the problem. Appreciate your reply!

oh nice! will check it out. And yes, good idea re: Thinkific. We tossed around that option too but it seemed like this GPT authentication route was the fastest option. Welp, that was before I knew how unreliable it is.

I tried Fort Knox style strict instructions with long and short phrasing…

It was still flakey… I spent 3 weeks on and off wondering WTF was going on…
