You can create a Custom GPT in ChatGPT that manages your Znift tasks. ChatGPT uses the OpenAPI specification to call the API directly.

​
Create a Custom GPT

1

Open GPT Builder

Go to chatgpt.com, click your profile icon, then My GPTs > Create a GPT.

Configure the GPT

In the Configure tab:
  • Name: Znift Tasks
  • Description: Manage your Znift tasks — create, complete, move, search, and review.
  • Instructions: Paste the following:
3

Add Actions

Scroll down to Actions > Create new action.Import from URL: Paste this URL and click Import:

Set up authentication

In the Actions authentication section:
  • Authentication type: API Key
  • API Key: Your Znift API key (from Profile > API Keys)
  • Auth Type: Custom
  • Custom Header Name: x-api-key
5

Save and test

Click Save (choose “Only me” or “Anyone with a link”).Try: “What do I have to do today?”

​
Example Prompts

Once your GPT is set up, try:
  • “What’s on my plate today?”
  • “Add a task for tomorrow: review the quarterly report”
  • “Mark the standup prep as done”
  • “How productive was I this week?”
  • “Search for tasks about the migration”
  • “Move the design review to next Monday”

​
Limitations

  • ChatGPT may ask for confirmation before each API call (this is normal for Actions)
  • Custom GPTs require a ChatGPT Plus or Team subscription
  • The GPT uses your API key stored in its configuration — do not share the GPT publicly if your key is embedded
