For years my Visual FoxPro program pulled mail from Yahoo without issue, right up until Yahoo switched to OAuth2 last September. Since that change the connection fails, and I can no longer download messages into my local VFP table. Chilkat supplies a sample PRG that retrieves and refreshes OAuth2 tokens for desktop apps, yet I’m not sure how to fold that code into my existing workflow. The routine that parses each message—headers, body, and any attachments—is already written and tested; what I need is the authentication and retrieval piece brought up to date. Scope of work • Use Chilkat’s VFP component to obtain and store a valid Yahoo OAuth2 access/refresh token. • Modify or replace my current POP/IMAP login so it authenticates with that token. • Return a simple wrapper that hands each downloaded message to my existing processing PRG, so mail once again lands in the same VFP table structure. • Include clear comments showing where to update client-id, client-secret, and redirect URI should Yahoo change them in the future. Acceptance criteria • Running the new PRG authenticates without manual browser steps after the initial token grant. • All unread messages download seamlessly into the table when I call my old routine. • Source code remains pure VFP with Chilkat only; no external .NET or DLL dependencies beyond Chilkat itself. If you have already linked VFP to modern OAuth2 services—or better yet to Yahoo—your expertise will save me a lot of time.

Hi, I’ve ever worked on similar legacy mail integrations including token storage, refresh and authenticated IMAP/POP retrieval before. I have checked the attached prg file, The current program already uses Chilkat IMAP, connects correctly to Yahoo, the main broken section is the login. For your project, I will use pure VFP and Chilkat to implement Yahoo’s OAuth2 flow and authenticate IMAP/POP using XOAUTH2. Then I’ll provide a clean wrapper that passes each downloaded message directly into your existing PRG, so your current header and body parsing and VFP table structure can remain unchanged. The initial Yahoo authorization will require the normal one time browser grant; after that, token refreshing and mail retrieval will run automatically without manual intervention. I’d recommend to rotate that Yahoo/app password and avoid keeping future secrets directly in the source file. I am a talented developer and have 9+ years experiences at IT companies. And I am open to a flexible work schedule, including different time zones and hours. Let’s start immediately. Thanks

Hi, I can update your existing Visual FoxPro Yahoo mail workflow to use modern OAuth2 authentication through Chilkat, while keeping your existing message-processing code and VFP table structure intact. I’ll focus specifically on the authentication/retrieval layer: obtaining and securely storing the Yahoo access/refresh tokens, refreshing the access token when required, and integrating token-based POP/IMAP authentication into your current PRG. I’ll also provide a simple wrapper that passes each downloaded message to your existing parser, so headers, body, and attachments continue through the workflow exactly as they do now. The solution will remain pure VFP with Chilkat as the only external dependency. I’ll clearly comment the client ID, client secret, redirect URI, token storage, and refresh logic so future Yahoo OAuth changes can be handled easily. I’m comfortable working with legacy VFP applications and modern OAuth2 integrations, and I can adapt the existing Chilkat Yahoo OAuth2 sample rather than unnecessarily rewriting your proven mail-processing logic. I can deliver clean, commented source code that meets your acceptance criteria and restores unattended message retrieval after the initial OAuth2 authorization.

Hi, I reviewed your Visual FoxPro Yahoo OAuth2 update request: your existing POP/IMAP login fails after Yahoo switched to OAuth2, stopping unread mail from landing in the same VFP table. I’ll use Chilkat’s VFP component to obtain and store Yahoo OAuth2 access/refresh tokens, then modify your login/authentication flow to authenticate with that token. I’ll wrap retrieval so each downloaded message is handed to your existing tested PRG that parses headers, body, and attachments, keeping the same table structure and adding clear comments for client-id, client-secret, and redirect URI. I focus on clean, debuggable VFP source and clear Technical Documentation so it runs without manual browser steps after the initial grant. Let’s discuss here now.

Hi there, Yahoo OAuth2 is exactly the point where your current VFP mail flow needs a clean authentication retrofit. I’ve solved this kind of integration before and can update your Chilkat-based PRG so it obtains and refreshes the Yahoo token, then passes each message straight into your existing parser and VFP table workflow. I’ll wire the Chilkat VFP component into your current POP/IMAP logic, keep the source pure VFP, and add clear comments for client-id, client-secret, and redirect URI updates. I’ll also preserve your tested message-processing routine and return a simple wrapper around it so unread mail lands in the same structure without changing your downstream code. Best regards, Ian

You need to restore your Visual FoxPro email workflow after Yahoo moved from password-based authentication to OAuth2, while keeping your existing message parsing and table structure unchanged. I have experience with API integrations, authentication flows, debugging legacy systems, and connecting older applications with modern services. I would focus only on the authentication and retrieval layer: integrating Chilkat’s VFP OAuth2 component, handling access/refresh token storage, updating IMAP/POP authentication, and creating a clean wrapper that passes downloaded messages into your existing processing PRG. The implementation would remain pure Visual FoxPro with Chilkat only, with clear comments for client ID, client secret, redirect URI, and token management. I would also test unread message retrieval and ensure the output matches your current VFP table workflow so your existing parser continues working without changes.

Yahoo killing basic auth broke this, common fix. Is your app pulling via IMAP or POP3? I would build a small OAuth2 token handler, since VFP cannot do the browser redirect flow natively, and wire the refresh token into your existing mail pull. Can start today, working fix in 3 to 5 days. Price and timeline here are based on the post, final numbers come after we go through your code. Let me know and I will send a plan.

Hello, I have just read your job description carefully. I can work directly with the existing VFP PRG and Chilkat component to update the Yahoo authentication flow without changing your existing message parsing logic. I understand the goal is to handle the initial OAuth2 grant, securely store and refresh the access token, authenticate through POP or IMAP, and pass each downloaded message into your existing processing routine and table structure. I can keep the implementation entirely in VFP with Chilkat and clearly comment the client ID, client secret, redirect URI, token storage, and refresh logic for future maintenance. I would first review your attached IMAP PRG and identify exactly where the current authentication needs to be replaced. One question is whether your current routine uses POP3 or IMAP for Yahoo? I look forward to hearing from you, Lautaro

Hi - Abror here "VFP YAHOO OAUTH2 MAIL RETRIEVAL" — you need the old mail workflow working again without touching your proven message parser. I’d keep the existing VFP processing intact and isolate OAuth2 into a small Chilkat-based wrapper that handles the initial grant, token refresh, and IMAP/POP authentication. I’ll also make the client ID, secret, and redirect URI easy to update if Yahoo changes its requirements. Can you share the current VFP mail-login PRG and the Chilkat sample you’re using?

Hello, I understand your Visual FoxPro program pulled mail from Yahoo fine for years until Yahoo switched to OAuth2 last September—since then the connection fails and you can't download messages into your local VFP table. Chilkat supplies a sample PRG for retrieving and refreshing OAuth2 tokens for desktop apps, but you need help folding it into your workflow.

I do exactly this kind of VFP + Chilkat OAuth2 modernization. The key is the token flow: an initial browser-based grant to get the refresh token, then automatic silent refresh so subsequent runs need no manual browser step—which is exactly your acceptance criterion. Pure VFP + Chilkat only, no external dependencies. Happy to confirm a couple of details and get started.

Hello, I can help update your existing Visual FoxPro mail workflow so it works with Yahoo's OAuth2 authentication while keeping your current message-processing logic and table structure intact. From your description, the parsing side is already tested, so I would focus specifically on the authentication and retrieval layer. I can integrate Chilkat's VFP OAuth2 flow to handle the initial authorization, securely store the access and refresh tokens, and automatically refresh the access token when required so your normal workflow does not require repeated browser authorization. I can then update or replace the existing POP/IMAP login with XOAUTH2 authentication and create a clean VFP wrapper that retrieves unread messages and passes each one directly into your existing processing PRG. The source will remain pure VFP using Chilkat only, with clear comments and configuration sections for the client ID, client secret, redirect URI, token storage, and refresh process. I can also document the flow so future maintenance is straightforward if Yahoo changes OAuth settings. I have experience debugging legacy applications, integrating APIs and authentication workflows, and connecting existing systems to modern services without disrupting established business logic. One key question: are you currently using Chilkat's IMAP component, POP3 component, or another library for the existing Yahoo mail retrieval? Best regards

Hi, First thing I'd build is the token piece, the Chilkat OAuth2 grab and refresh cycle, wired up and saved to disk before it touches your mail code at all. That way you can see it authenticate against Yahoo on its own, no guessing whether a login failure is a token problem or a parsing problem later on. Once that's solid, I'll swap out your old POP/IMAP login for a token-based one and write a thin wrapper that hands each message straight to your existing PRG. I've dealt with this exact Yahoo OAuth2 break before, so I know where Chilkat's sample code gets clunky in a real VFP app. I'll comment the client-id, secret, and redirect URI spots clearly so you can update them yourself down the road. Refresh tokens can go stale quietly, so I'll add a check that flags it instead of just failing silently. This is about a day of work start to finish, pure VFP and Chilkat, nothing else bolted on. Ready to start when you are. Best, Emrah
