Más de este repositorio langchain-deploy-integration Deploy a LangChain 1.0 / LangGraph 1.0 app to Cloud Run, Vercel, or LangServe correctly — with timeouts sized for chain length, cold-start mitigation, SSE anti-buffering headers, and Secret Manager over .env.

langchain-langgraph-agents Build a correct LangGraph 1.0 ReAct agent with create_react_agent — typed tools, error propagation, recursion caps, and stop conditions that actually stop. Use when writing a first tool-calling agent, migrating from AgentExecutor or initialize_agent, or diagnosing an agent that loops on vague prompts.

langchain-langgraph-human-in-loop Build LangGraph 1.0 human-in-the-loop approval flows with interrupt_before /
interrupt_after and Command(resume=...) — JSON-serializable state, clean
resume semantics, and UI wiring for approval decisions. Use when adding an
approval gate before an expensive tool call, wiring a Slack/web UI for agent
approvals, or debugging a graph that crashes on interrupt.

Instantly Upgrade Migration: API v1 to v2
Overview
Migrate from Instantly API v1 (deprecated January 2026) to API v2. Key changes: Bearer token auth replaces query-string API keys, REST-standard endpoints replace legacy paths, scoped API keys replace single global key, and cursor-based pagination replaces offset pagination. Existing v1 integrations via Zapier/Make continue working, but new integrations must use v2.
Prerequisites
Existing Instantly API v1 integration
Access to Instantly dashboard to generate v2 API keys
Understanding of Bearer token authentication
Migration Map
Authentication Change
const v1Url = `https://api.instantly.ai/api/v1/campaign/list?api_key=${API_KEY} ` ;
const v2Response = await fetch ("https://api.instantly.ai/api/v2/campaigns" , {
headers : { Authorization : `Bearer ${API_KEY} ` },
});

Request Body Changes
const v1Body = {
api_key : "your-key" ,
name : "Campaign Name" ,
};
const v2Body = {
name : "Campaign Name" ,
campaign_schedule : {
start_date : "2026-04-01" ,
schedules : [{
name : "Business Hours" ,
timing : { from : "09:00" , to : "17:00" },
days : { "1" : true , "2" : true , "3" : true , "4" : true , "5" : true , "0" : false , "6" : false },
timezone : "America/New_York" ,
}],
},
sequences : [{
steps : [{
type : "email" ,
delay : 0 ,
variants : [{ subject : "Hello {{firstName}}" , body : "Hi {{firstName}}..." }],
}],
}],
};
Lead Operation Changes
const v1AddLeads = {
api_key : "your-key" ,
campaign_id : "campaign-uuid" ,
leads : [
{ email : "user@example.com" , first_name : "Jane" },
],
};
const v2AddLead = {
campaign : "campaign-uuid" ,
email : "user@example.com" ,
first_name : "Jane" ,
skip_if_in_workspace : true ,
verify_leads_on_import : true ,
custom_variables : { role : "CTO" },
};
Instructions
Step 1: Audit Existing v1 Calls set -euo pipefail
grep -rn "api/v1/" src/ --include="*.ts" --include="*.js" --include="*.py" || echo "No v1 calls found"
grep -rn "api_key=" src/ --include="*.ts" --include="*.js" --include="*.py" || echo "No query-string keys found"
Step 2: Create Migration Adapter
export class InstantlyV1ToV2Adapter {
private apiKey : string ;
private baseUrl = "https://api.instantly.ai/api/v2" ;
constructor (apiKey : string this .apiKey = apiKey;
}
private async request<T>(path : string , options : RequestInit = {}): Promise <T> {
const res = await fetch (`${this .baseUrl} ${path} ` , {
...options,
headers : {
"Content-Type" : "application/json" ,
Authorization : `Bearer ${this .apiKey} ` ,
...options.headers ,
},
});
if (!res.ok ) throw new Error (`Instantly ${res.status} : ${await res.text()} ` );
return res.json () as Promise <T>;
}
async listCampaigns (return this .request ("/campaigns?limit=100" );
}
async getCampaign (campaignId : string return this .request (`/campaigns/${campaignId} ` );
}
async launchCampaign (campaignId : string return this .request (`/campaigns/${campaignId} /activate` , { method : "POST" });
}
async pauseCampaign (campaignId : string return this .request (`/campaigns/${campaignId} /pause` , { method : "POST" });
}
async addLeads (campaignId : string , leads : Array <{ email: string ; first_name?: string }>const results = [];
for (const lead of leads) {
const result = await this .request ("/leads" , {
method : "POST" ,
body : JSON .stringify ({
campaign : campaignId,
email : lead.email ,
first_name : lead.first_name ,
skip_if_in_workspace : true ,
}),
});
results.push (result);
}
return results;
}
async getCampaignAnalytics (campaignId : string return this .request (`/campaigns/analytics?id=${campaignId} ` );
}
}
Step 3: Pagination Migration
async function * paginateV2<T extends { id : string }>(
path : string ,
pageSize = 100
): AsyncGenerator <T[]> {
let startingAfter : string | undefined ;
while (true ) {
const qs = new URLSearchParams ({ limit : String (pageSize) });
if (startingAfter) qs.set ("starting_after" , startingAfter);
const page = await instantly<T[]>(`${path} ?${qs} ` );
if (page.length === 0 ) break ;
yield page;
startingAfter = page[page.length - 1 ].id ;
if (page.length < pageSize) break ;
}
}
Step 4: New v2 Features to Adopt
await instantly ("/api-keys" , {
method : "POST" ,
body : JSON .stringify ({ name : "analytics-only" , scopes : ["campaigns:read" ] }),
});
await instantly ("/subsequences" , {
method : "POST" ,
body : JSON .stringify ({
parent_campaign : campaignId,
name : "Re-engage interested leads" ,
conditions : { crm_status : [1 ] },
}),
});
await instantly ("/inbox-placement-tests" , {
method : "POST" ,
body : JSON .stringify ({
name : "Pre-launch deliverability test" ,
email_subject : "Test Subject" ,
email_body : "Test body content" ,
type : 1 ,
}),
});
await instantly ("/block-lists-entries/bulk-create" , {
method : "POST" ,
body : JSON .stringify ({
entries : ["competitor.com" , "internal.com" ],
}),
});
Migration Checklist
Error Handling Error Cause Solution 401 on v2Using v1 key format Generate new v2 Bearer token 404 on v2 pathUsing v1 endpoint path Check migration table above 422 on lead addNew validation rules in v2 Add required fields per v2 schema Missing pagination data Using skip instead of starting_after Convert to cursor pagination
