Overview

Debugging toolkit for Gamma API integration issues. Includes connectivity tests, request tracing, diagnostic scripts, and support ticket templates. Gamma uses a REST API at https://public-api.gamma.app/v1.0/ with X-API-KEY header authentication.

Prerequisites

• Active Gamma integration
• Node.js 18+ or Python 3.10+
• curl and jq available

Instructions

Step 1: Quick Connectivity Test (curl)

#!/bin/bash
set -euo pipefail
echo "=== Gamma API Diagnostic ==="

# 1. Check API key
if [ -z "${GAMMA_API_KEY:-}" ]; then
  echo "FAIL: GAMMA_API_KEY not set"; exit 1
fi
echo "OK: API key set (${#GAMMA_API_KEY} chars, prefix: ${GAMMA_API_KEY:0:4}...)"

# 2. Test authentication via /themes endpoint
STATUS=$(curl -s -o /dev/null -w "%{http_code}" \
  -H "X-API-KEY: $GAMMA_API_KEY" \
  "https://public-api.gamma.app/v1.0/themes")
if [ "$STATUS" = "200" ]; then
  echo "OK: Authentication successful"
elif [ "$STATUS" = "401" ]; then
  echo "FAIL: Invalid API key (401)"
elif [ "$STATUS" = "403" ]; then
  echo "FAIL: Account not on Pro+ plan (403)"
else
  echo "WARN: Unexpected status $STATUS"
fi

# 3. Check latency
echo "--- Latency (3 samples) ---"
for i in 1 2 3; do
  LATENCY=$(curl -s -o /dev/null -w "%{time_total}" \
    -H "X-API-KEY: $GAMMA_API_KEY" \
    "https://public-api.gamma.app/v1.0/themes")
  echo "  Request $i: ${LATENCY}s"
done

# 4. List themes (verify API access)
echo "--- Workspace Themes ---"
curl -s -H "X-API-KEY: $GAMMA_API_KEY" \
  "https://public-api.gamma.app/v1.0/themes" | jq '.[].name' 2>/dev/null || echo "Could not parse themes"

Step 2: TypeScript Diagnostic Script

// scripts/gamma-diagnose.ts
const BASE = "https://public-api.gamma.app/v1.0";
const headers = {
  "X-API-KEY": process.env.GAMMA_API_KEY!,
  "Content-Type": "application/json",
};

interface TestResult {
  test: string;
  status: "PASS" | "FAIL";
  detail: string;
  latencyMs?: number;
}

async function diagnose(): Promise<TestResult[]> {
  const results: TestResult[] = [];

  // Test 1: API key set
  if (!process.env.GAMMA_API_KEY) {
    results.push({ test: "API Key", status: "FAIL", detail: "GAMMA_API_KEY not set" });
    return results;
  }
  results.push({
    test: "API Key",
    status: "PASS",
    detail: `Set (${process.env.GAMMA_API_KEY.length} chars)`,
  });

  // Test 2: Authentication
  try {
    const start = Date.now();
    const res = await fetch(`${BASE}/themes`, { headers });
    const latency = Date.now() - start;
    if (res.ok) {
      const themes = await res.json();
      results.push({
        test: "Authentication",
        status: "PASS",
        detail: `OK, ${themes.length} themes available`,
        latencyMs: latency,
      });
    } else {
      results.push({
        test: "Authentication",
        status: "FAIL",
        detail: `HTTP ${res.status}: ${await res.text()}`,
      });
    }
  } catch (err: any) {
    results.push({ test: "Authentication", status: "FAIL", detail: err.message });
  }

  // Test 3: Folders endpoint
  try {
    const start = Date.now();
    const res = await fetch(`${BASE}/folders`, { headers });
    results.push({
      test: "Folders API",
      status: res.ok ? "PASS" : "FAIL",
      detail: res.ok ? `${(await res.json()).length} folders` : `HTTP ${res.status}`,
      latencyMs: Date.now() - start,
    });
  } catch (err: any) {
    results.push({ test: "Folders API", status: "FAIL", detail: err.message });
  }

  // Test 4: Generation (dry-run style — creates a minimal generation)
  try {
    const start = Date.now();
    const res = await fetch(`${BASE}/generations`, {
      method: "POST",
      headers,
      body: JSON.stringify({
        content: "Diagnostic test: one card about testing",
        outputFormat: "presentation",
      }),
    });
    if (res.ok) {
      const { generationId } = await res.json();
      results.push({
        test: "Generation API",
        status: "PASS",
        detail: `Started: ${generationId}`,
        latencyMs: Date.now() - start,
      });
      // Note: this consumes credits — skip in automated tests
    } else {
      results.push({
        test: "Generation API",
        status: "FAIL",
        detail: `HTTP ${res.status}: ${await res.text()}`,
      });
    }
  } catch (err: any) {
    results.push({ test: "Generation API", status: "FAIL", detail: err.message });
  }

  // Print report
  console.log("\n=== Gamma Diagnostic Report ===");
  for (const r of results) {
    const latency = r.latencyMs ? ` (${r.latencyMs}ms)` : "";
    console.log(`  [${r.status}] ${r.test}: ${r.detail}${latency}`);
  }
  const failures = results.filter((r) => r.status === "FAIL").length;
  console.log(`\n${results.length} tests, ${failures} failures\n`);

  return results;
}

diagnose();

Run: npx tsx scripts/gamma-diagnose.ts

Step 3: Debug Client with Request Logging

// src/gamma/debug-client.ts
export function createDebugGammaClient(apiKey: string) {
  const base = "https://public-api.gamma.app/v1.0";
  const headers = { "X-API-KEY": apiKey, "Content-Type": "application/json" };

  async function debugRequest(method: string, path: string, body?: unknown) {
    const start = Date.now();
    const url = `${base}${path}`;
    console.log(`[GAMMA] ${method} ${path}`, body ? JSON.stringify(body).slice(0, 200) : "");

    const res = await fetch(url, {
      method,
      headers,
      body: body ? JSON.stringify(body) : undefined,
    });

    const duration = Date.now() - start;
    const responseText = await res.text();
    const status = res.ok ? "OK" : "ERROR";

    console.log(`[GAMMA] ${status} ${res.status} in ${duration}ms`);
    if (!res.ok) {
      console.log(`[GAMMA] Response: ${responseText.slice(0, 500)}`);
    }

    if (!res.ok) throw new Error(`Gamma ${res.status}: ${responseText}`);
    return JSON.parse(responseText);
  }

  return {
    generate: (body: any) => debugRequest("POST", "/generations", body),
    poll: (id: string) => debugRequest("GET", `/generations/${id}`),
    listThemes: () => debugRequest("GET", "/themes"),
    listFolders: () => debugRequest("GET", "/folders"),
  };
}
