Getting Started

Stream's Moderation API lets you integrate content moderation into any application. This guide walks you through installation, configuration, and your first moderation check.

Installation

go get github.com/GetStream/getstream-go/v4

Initialize the Client

package main

import (
    "context"
    getstream "github.com/GetStream/getstream-go/v4"
)

func main() {
    client := getstream.NewStream("YOUR_API_KEY", "YOUR_API_SECRET")
    ctx := context.Background()
}

Create a Moderation Policy

Before checking content, create a moderation configuration that defines which rules to apply:

_, err := client.Moderation().UpsertConfig(ctx, &getstream.UpsertConfigRequest{
    Key: "my_config",
    AiTextConfig: &getstream.AiTextConfig{
        Rules: []getstream.AiTextRule{
            {Label: "SPAM", Action: "flag"},
            {Label: "HARASSMENT", Action: "remove"},
        },
    },
    BlockListConfig: &getstream.BlockListConfig{
        Rules: []getstream.BlockListRule{
            {Name: "profanity_en", Action: "remove"},
        },
    },
})

For Stream Chat, use config key chat:messaging. For Stream Feeds, use feeds. See Configuration for details.

Check Content

response, err := client.Moderation().Check(ctx, &getstream.CheckRequest{
    EntityType:      "stream:chat:v1:message",
    EntityID:        "message-123",
    EntityCreatorID: "user-456",
    ModerationPayload: &getstream.ModerationPayload{
        Texts: []string{"Hello, this is a test message"},
    },
    ConfigKey: getstream.PtrTo("my_config"),
})

fmt.Println(response.Data.RecommendedAction) // "keep", "flag", or "remove"

Handle the Response

The response includes:

  • RecommendedAction -- "keep", "flag", or "remove"
  • Status -- "complete" or "partial" (if async checks are still running)
  • Item -- the review queue item (if content was flagged or removed)
switch response.Data.RecommendedAction {
case "keep":
    // Content is safe, no action needed
case "flag":
    // Content is suspicious, send to review queue
    fmt.Println("Flagged for review:", response.Data.Item)
case "remove":
    // Content violates policies, remove it
    fmt.Println("Content removed:", response.Data.Item)
}
