wa-setup — Connect WhatsApp via Wasender

Goal: by the end of this skill, the user has a working Wasender session, a phone connected by QR scan, and a .env file with all credentials saved. You do every technical step. The user just signs up, holds their phone, scans a QR.

Speak Hebrew to the user.

Step 0 — Frame what's about to happen

Tell the user (in Hebrew):

נחבר עכשיו את הוואטסאפ שלך לשירות שנקרא Wasender. זה השירות שמאפשר לבוט לקרוא ולשלוח הודעות בשמך.

חשוב שתדע:

המספר שתחבר צריך להיות מספר נפרד — מספר ייעודי לבוט (חדש, או SIM ישנה שלא בשימוש). זה לא חובה, אבל זה הכי בטוח. ❗ זה לא הוואטסאפ הרשמי לעסקים — יש סיכון תיאורטי לחסימה אם משתמשים במספר אישי.

עלות: ניסיון חינם של 3 ימים, אחרי זה $6 לחודש למספר אחד.

מוכן להתחיל?

Wait for confirmation.

Step 1 — Sign up at Wasender

Tell the user:

פתח את הדפדפן וגש ל: https://wasenderapi.com

לחץ על Sign Up והשלם הרשמה (אימייל + סיסמה).

אמת את האימייל.

אחרי שנכנסת — תגיד לי "מחובר" ונמשיך.

Wait until the user confirms.

Step 2 — Get the Personal Access Token (PAT)

Tell the user:

מצוין. עכשיו ניצור Personal Access Token — מפתח שיאפשר לי לנהל בשמך את החיבורים לוואטסאפ.

גש ל: https://wasenderapi.com/settings/tokens

לחץ Create New Token, תן לו שם (למשל "claude-code-builder").

העתק את המחרוזת שתופיע — זו ההזדמנות היחידה שלך לראות אותה.

הדבק את המחרוזת כאן בצ'אט.

When the user pastes the token:

Do not echo it back.
Read the existing .env file at the project root if it exists. If not, create it.
Add or update the line WASENDER_PAT=<the token>.
Make sure .env is in .gitignore. If not, add it.
Confirm to the user:

מעולה. שמרתי את ה-PAT ב-.env מקומית (לא מועלה ל-Git, אל דאגה). עכשיו ניצור את החיבור עצמו.

Step 3 — Create a WhatsApp session via API

Ask the user for the phone number they'll connect:

איזה מספר טלפון תרצה לחבר? (פורמט בינלאומי עם +, למשל +972501234567)

Validate format. Then ask:

איך נקרא לחיבור הזה? (למשל "הסוכן של רינת")

Then make the API call. Use Bash with curl. Pull the PAT from .env, never hardcode it in your prompt or output.

curl -sX POST "https://www.wasenderapi.com/api/whatsapp-sessions" \
  -H "Authorization: Bearer $WASENDER_PAT" \
  -H "Content-Type: application/json" \
  -d "{
    \"name\": \"$SESSION_NAME\",
    \"phone_number\": \"$PHONE_NUMBER\",
    \"account_protection\": true,
    \"log_messages\": true,
    \"webhook_enabled\": false
  }"

(Webhook URL is registered later in wa-deploy once we have a public URL.)

The response shape:

{
  "success": true,
  "data": {
    "id": 1,
    "api_key": "75075a7bf6417bff59e76fb...",
    "webhook_secret": "fb61be92ddb7935e0cedcec58e470f6c",
    "status": "need_scan",
    "phone_number": "+972501234567"
  }
}

Parse the response. Save to .env:

WASENDER_SESSION_ID=<id>
WASENDER_API_KEY=<api_key>
WASENDER_WEBHOOK_SECRET=<webhook_secret>
WASENDER_PHONE=<phone_number>

Also update .wa-state.json:

{ "wasender_session_id": <id>, "wasender_phone": "<phone>" }

If the API returns success: false, surface the error message in Hebrew and stop. Common errors:

401: PAT is invalid → ask the user to regenerate.
422: phone number format → ask again with valid E.164.
402: plan limit reached → tell the user to upgrade.

Step 4 — Connect the session and fetch the QR

curl -sX POST "https://www.wasenderapi.com/api/whatsapp-sessions/$WASENDER_SESSION_ID/connect" \
  -H "Authorization: Bearer $WASENDER_PAT"

Then poll for the QR:

curl -sX GET "https://www.wasenderapi.com/api/whatsapp-sessions/$WASENDER_SESSION_ID/qrcode" \
  -H "Authorization: Bearer $WASENDER_PAT"

Response: {"success":true,"data":{"qrCode":"2@DfzdTHe..."}} — the qrCode value is the raw WhatsApp QR string, not an image.

Render it as an image so the user can scan. Use Python:

python -c "
import qrcode, sys, os
qr_str = os.environ['QR_STR']
img = qrcode.make(qr_str)
img.save('wa-qr.png')
print('saved wa-qr.png')
"

If qrcode isn't installed, run pip install qrcode[pil] first. Save the image to the project root as wa-qr.png and tell the user:

הקוד מוכן! נשמר אצלך כאן: wa-qr.png

עכשיו:

פתח את הוואטסאפ בטלפון שאתה רוצה לחבר.

הגדרות → מכשירים מקושרים → קישור מכשיר.

סרוק את הקובץ wa-qr.png.

⏱️ הקוד תקף ל-45 שניות. אם פג תוקף, אגיד לך ונייצר חדש.

Step 5 — Wait for connection

Poll status every 3 seconds for up to 90 seconds:

curl -sX GET "https://www.wasenderapi.com/api/status" \
  -H "Authorization: Bearer $WASENDER_API_KEY"

Response: {"success":true,"data":{"status":"connected"|"connecting"|"need_scan"|"disconnected"}}

connected → success, move to step 6.
need_scan after 45s → QR expired. Re-fetch QR, regenerate wa-qr.png, ask user to scan again.
disconnected → ask user if they want to retry from the start.

When connected, delete wa-qr.png (no need to leave it lying around) and tell the user:

🎉 חובר! המספר {phone} מחובר עכשיו דרך Wasender.

Step 6 — End-to-end verification

Send a test message from the bot back to itself (or to a number the user provides) to confirm outbound works.

Ask:

רוצה לשלוח הודעת בדיקה? אני אשלח "שלום מהבוט שלך 👋" למספר שתבחר. שלח לי את המספר (פורמט +).

Then:

curl -sX POST "https://www.wasenderapi.com/api/send-message" \
  -H "Authorization: Bearer $WASENDER_API_KEY" \
  -H "Content-Type: application/json" \
  -d "{\"to\":\"$TEST_NUMBER\",\"text\":\"שלום מהבוט שלך 👋\"}"

Verify response has success: true and data.msgId. Ask the user:

קיבלת את ההודעה?

If yes — done. If no — diagnose: check status endpoint, check rate limit headers, check sender format.

Step 7 — Update state and hand back

Update .wa-state.json:

{
  "current_stage": "characterize",
  "completed_stages": ["setup"],
  "last_updated": "<ISO 8601>"
}

Tell the user:

נהדר! החיבור עובד. השלב הבא הוא לעצב את האישיות של הבוט — מה השם שלו, מי הוא משרת, איך הוא מדבר, מה מותר ומה אסור.

מוכן להמשיך לשלב הגדרת אופי הבוט (/wa ישלוף אותך לשם)?

Hand back to /wa orchestrator.

Common pitfalls and how to handle

PAT pasted with spaces or quotes. Strip whitespace and surrounding quotes before saving.
User on free tier hits "1 request per minute" limit. When polling status, respect 3-second intervals — don't burst. If 429 returned, wait longer.
User has a previously deleted session with the same phone. The create call may return an error about duplicate phone. Tell the user we'll re-use the existing session — call GET /api/whatsapp-sessions (with PAT) to list, find the matching one, and adopt its id/api_key/webhook_secret.
qrcode Python lib not installed. Install via pip silently first; only mention it to the user if install fails.
Webhook secret missing from response. This shouldn't happen on a fresh session, but if it does, regenerate via PUT /api/whatsapp-sessions/{id} with regenerate_webhook_secret: true (verify against current docs if needed).
