## Overview
You can use a tag manager to dynamically inject Affirm-related scripts on the promotions.
## Google Tag Manager
[GTM](🔗) includes a feature to sequence tag execution, so that you can make sure Affirm JS is always loaded first.
## Promos
Here is an example of how that would be setup:
| Tag # | Contents | Location | Trigger |
| Tag 1 | [Affirm JS embed code](🔗) | All pages | page load (auto) |
| Tag 2 | Affirm [promo html](🔗) | Only pages where promo should be displayed | Fires after 'Tag 1' |
Below is a screenshot of how these settings look in GTM:
## Checkout
| Tag # | Contents | Location | Trigger |
| Tag 1 | [Affirm JS embed code](🔗) | All pages | page load (auto) |
| Tag 2 | Affirm [promo html](🔗) | Only pages where promo should be displayed | Fires after 'Tag 1' |
