Google Flow creates cinematic AI clips with Veo, images with Imagen 4 and Nano Banana / Gemini 2.5 Flash Image.

Create a dedicated Gmail account

⚠️ Use a dedicated Gmail account for this API - do NOT use your personal Gmail account.

If you already have a dedicated Gmail account for AI/API services, you can use that. Otherwise, create a new one.

When creating a new account:

  1. Enable 2-Step Verification
  2. Use Google Authenticator for verification codes

Clear all browser cookies

⚠️ Do NOT use Google Chrome. Google’s integration with Chrome will interfere with cookie extraction.

Use one of these browsers instead:

If using Opera, enable VPN and set region to Americas.

You must clear ALL cookies before proceeding to start with a fresh session.

Open browser settings and select Delete browsing data... 1

Select time range to be All time 1 and check Cookies and other site data 2, click Delete data 3

Navigate to https://labs.google/fx/tools/flow and click on Sign in with Google button 1

Enter your Google email created earlier 1

Enter 2-Step Verification code 1

⚠️ You MUST check Don't ask again on this device 2 - skipping this will break the API session.

Once successfully logged in you should see New project button

Navigate to https://myaccount.google.com/

Copy https://accounts.google.com/ cookies

  1. Open Developer Tools: right-click anywhere on page → select Inspect (or press F12)

  1. Go to Application tab 1
  2. Select Cookies → https://accounts.google.com/ 2
  3. Select all cookies in the right panel (Ctrl+A) and copy (Ctrl+C) 3

Your copied cookies will look similar to this (values redacted):

Verify cookies value

Paste your cookies below and click Go to verify. You should receive HTTP 200 if successful.

⚠️ This step only VERIFIES your cookies - it does NOT add your account!

After successful verification, you MUST proceed to POST /accounts to actually add and configure your Google Flow API account.

⚠️ CRITICAL - Do this immediately after successful verification:

  1. Open a new empty tab
  2. Close all other tabs
  3. Clear all browser cookies
  4. Do NOT restart the browser

⚠️ The API now manages this Google account session.

Do NOT access this Google account via AI Studio or Google Flow directly (browser or any other means). Using the same account through both the API and direct access will break the session and require you to redo this entire setup.

Configure Captcha Providers

Image and video generation requires reCAPTCHA v3 Enterprise solving.

Users receive 100 free captcha credits when adding their first Google Flow account. These credits are used automatically, so you can start generating images and videos right away without configuring any provider. Check your remaining credits via GET /accounts/captcha-providers.

After free credits are exhausted, you must configure at least one provider’s API key before using POST /images, POST /images/upscale, or POST /videos.

Supported Providers:

Provider Cost Website
EzCaptcha (Recommended) ~$2.50 per 1,000 solves ez-captcha.com
CapSolver ~$3.00 per 1,000 solves capsolver.com
YesCaptcha varies yescaptcha.com

Setup Steps:

  1. Create an account with one or more providers above
  2. Purchase credits and obtain your API key from the provider’s dashboard
  3. Configure your API key(s) using POST /accounts/captcha-providers

Recommendations:

  • We have thoroughly tested EzCaptcha and recommend it as the primary provider. Other providers will also work but may have lower success rates.
  • Configure multiple providers for redundancy (if one fails or returns rejected tokens, the API automatically retries with the next provider)
  • Each image/video generation attempt requires one captcha solve (~$2.50-$3.00 per 1,000 generations)
