*Thank you for your help!*



*Here is the process, as presented to me by ChatGPT. My ultimate goal.
goal was to shorten the manifest URL to a small QR code to print on a label
I wanted to attach as a certificate of authenticity to my large metal print
for an exhibit in a gallery. *


*At the same time, I wanted to present my steps in a presentation I am
giving in a week.....*

*:scroll: How to Get Your C2PA Manifest URL Link*




When you *export an image with Content Credentials (C2PA) enabled* in
*Lightroom
Classic or Photoshop*, Adobe generates a *C2PA Manifest URL* that allows
buyers, collectors, and galleries to verify your image’s authenticity.

*:pushpin: Steps to Get Your C2PA Manifest URL*


*:white_heavy_check_mark: Method 1: Using Adobe’s Content Credentials Verify Tool*

1. *Go to* Adobe’s Content Credentials Verification Page
<>.

2. *Upload your image* (JPG, PNG, or TIFF with C2PA credentials).

3. Once uploaded, *click “View Details”*.

4. Copy the *Manifest URL* from the page.


:pushpin: *This URL is your public verification link*, which you can share with
collectors, galleries, or include on your Certificate of Authenticity.

*:white_heavy_check_mark: Method 2: Finding the Manifest URL in Photoshop*

1. Open *Photoshop* and load your *exported image with Content Credentials*.

2. Go to *Window > Content Credentials (Beta)*.

3. Click *“Verify”* – this will open a browser with your image’s
verification page.

4. *Copy the URL from your browser* – this is your *C2PA Manifest Link*.

*:white_heavy_check_mark: Method 3: Finding the Manifest URL in Lightroom Classic*

1. *Select your exported image* in Lightroom Classic.

2. Go to *Metadata Panel* and check for *Content Credentials data*.

3. If the *Manifest URL* isn’t visible, upload your image to
contentcredentials.org/verify to retrieve it.

*:pushpin: Where to Use Your C2PA Manifest URL*

• *Embed it in metadata* (Copyright URL field).

• *Include it on your Certificate of Authenticity*.

• *Share with galleries and collectors* for verification.

• *Generate a QR Code* linking to the URL.


Would you like a guide on *creating a QR code for your C2PA Manifest URL*?

Looks like you have the AI answers you need to get the URL... But do they actually work?  :]  This wasn't the case in my test.

Thank you for your response and confirming that ChatGPT just hallucinated.
When I challenged it, it admitted the error:

*"You’re absolutely right to double-check how Adobe Content Credentials
(C2PA) works. Let’s go over the correct process of how and where the C2PA
Manifest URL is stored, retrieved, and used—ensuring accur*

*:keycap_1: Does Adobe Automatically Generate a Public URL for Every Image with
C2PA?*

*:cross_mark: No, Adobe does not automatically generate a public URL when you export
an image with Content Credentials enabled in Photoshop or Lightroom Classic*

*:police_car_light: Key Difference from What I Previously Said:*

* • There is no permanent, automatically generated public URL for the
image’s certificate.• You (or anyone verifying) must upload the image
manually to the verification site to check the credentials.*


Given that Adobe's C2PA is still in beta, it is understandable, but I have
to be more careful with ChatGPT.


Thank you so much.

Wouldn't you get that directly from the CA (certificate authority)?
