Why Prisma instead of integrating G2 yourself

With Prisma

One API key for every platform
One JSON format: rating, text, author, reply, url
Signed webhooks for new reviews and replies
History kept from the day you connect
Test keys with sample data before going live

G2 on your own

An API token from the G2 Developer Portal, valid for a year
Review access depends on the vendor’s G2 plan
Answers split into “like best / dislike” fields
No reply endpoint: the API only says whether you responded

Three steps to G2 reviews in your product

Connect

The software vendor gives Prisma a G2 API token and, optionally, which products to import. Create the token in the G2 Developer Portal → Access Tokens. products is optional: without it Prisma imports the products your account owns.

curl -X POST https://api.prismareviews.com/v1/connections \
  -H "Authorization: Bearer $PRISMA_API_KEY" \
  -H "Content-Type: application/json" \

    "platform": "g2",
    "credentials": {
      "api_token": "<g2 api token>",
      "products": [
        "acme-crm"
      ]
    }

Frequently asked questions

Can I reply to G2 reviews through the API?

Read only: G2 has no public reply API. Every review includes a link to answer it on the platform, so your team answers it on G2.

How do my customers connect G2?

The software vendor gives Prisma a G2 API token and, optionally, which products to import.

What happens if I send a reply to a G2 review?

No. G2 doesn't let third parties publish replies through an API, so Prisma is read only there: POST /v1/reviews/{id}/reply returns 422 reply_not_supported. Every review includes url, a link to answer it in G2.

Why are G2 ratings whole numbers?

G2 allows half stars. Prisma rounds them to a 1–5 whole number so they match the other platforms.

Which plan includes it?

Every paid plan, from Beam (€49 a month for 10 locations). The free Spark plan covers the platforms with official reply APIs. Each listing or store counts as one location.
